The Range of Statistical Data Sets

The Range of Statistical Data Sets In statistics and mathematics, the range is the difference between the maximum and minimum values of a data set and serve as one of two important features of a data set. The formula for a range is the maximum value minus the minimum value in the dataset, which provides statisticians with a better understanding of how varied the data set is. Two important features of a data set include the center of the data and the spread of the data, and the center can be ​measured in a number of ways: the most popular of these are the mean, median, mode, and midrange, but in a similar fashion, there are different ways to calculate how spread out the data set is and the easiest and crudest measure of spread is called the range. The calculation of the range is very straightforward. All we need to do is find the difference between the largest data value in our set and the smallest data value. Stated succinctly we have the following formula: Range Maximum Value–Minimum Value. For example, the data set 4,6,10, 15, 18 has a maximum of 18, a minimum of 4 and a range of 18-4 14. Limitations of Range The range is a very crude measurement of the spread of data because it is extremely sensitive to outliers, and as a result, there are certain limitations to the utility of a true range of a data set to statisticians because a single data value can greatly affect the value of the range. For example, consider the set of data 1, 2, 3, 4, 6, 7, 7, 8. The maximum value is 8, the minimum is 1 and the range is 7. Then consider the same set of data, only with the value 100 included. The range now becomes 100-1 99 wherein the addition of a single extra data point greatly affected the value of the range. The standard deviation is another measure of spread that is less susceptible to outliers, but the drawback is that the calculation of the standard deviation is much more complicated. The range also tells us nothing about the internal features of our data set. For example, we consider the data set 1, 1, 2, 3, 4, 5, 5, 6, 7, 8, 8, 10 where the range for this data set is 10-1 9.  If we then compare this to the data set of 1, 1, 1, 2, 9, 9, 9, 10. Here the range is, yet again, nine, however, for this second set and unlike the first set, the data is clustered around the minimum and maximum. Other statistics, such as the first and third quartile, would need to be used to detect some of this internal structure. Applications of Range The range is a good way to get a very basic understanding of how spread out numbers in the data set really are because it is easy to calculate as it only requires a basic arithmetic operation, but there are also a few other applications of the range of a data set in statistics. The range can also be used to estimate another measure of spread, the standard deviation. Rather than go through a fairly complicated formula to find the standard deviation, we can instead use what is called the range rule. The range is fundamental in this calculation. The range also occurs in a boxplot, or box and whiskers plot. The maximum and minimum values are both graphed at the end of the whiskers of the graph and the total length of the whiskers and box is equal to the range.

Allogeneic MCSs to make Cartilage for Knee Function

Allogeneic MCSs to make Cartilage for Knee Function    INTRODUCTION: – 1.1 What is Osteoarthritis? Articular cartilage is a highly resilient hyaline tissue composed of chondrocytes and surrounded by extracellular matrix present in a joint which act as shock absorber, protects the bones from the friction and wear and helps in smooth movement of the joint (Bhumiratana et al. 2014). Osteoarthritis is a disease of joint where lack of cartilage causes musculoskeletal pain and restriction of the movement or disability of the joint for the patient. (Ahmed and Hincke, 2010) (Duthey, 2015). Reasons for cartilage damage are: – The impact / blow caused during sport activities or accident Wear and tear because of overuse of a joint (Observed in elderly people) Lack of movement (Medical News Today, 2017) Figure No.1. Osteoarthritis Affected Region Image Source: – www.osteoosteoOsteoarthritisresearchuk.org Osteoarthritis can affect any joint present in the body. As the knee-joint Osteoarthritis is the most commo n type of Osteoarthritis, in this report, we will discuss about knee-joint Osteoarthritis only. Tibiofemoral and patellofemoral are the two articular surfaces that the knee consists of. As it can be seen in the below image, the damaged cartilage, reduces the gap between joint and friction is generated between the bones which ultimately results in bone erosion and causes muscle pain or inflammation or restriction to the movement. Figure No.2. Osteoarthritis affected Knee Image Source: – http://www.bupa.co.uk/health-information/directory/o/Osteoarthritis Osteoarthritis is estimated to affect 250 million people worldwide. Osteoarthritis sufferers include men and women, children and adults. And according to World Health Organization, 30% of men and women over the age of 65 have Osteoarthritis (Woolf and Pfleger, 2003). Worldwide, 9.6% of men and 18.0% of women over the age of 60 years have symptomatic Osteoarthritis. Approximately 80% of those with Osteoarthritis will have limit ations in movement, and 25% cannot perform their major activities of daily life (Duthey, 2015). Figure No.3. Prevalence of Osteoarthritis of Knee Image Source: – Burden of major musculoskeletal conditions, Bulletin of the WHO 2003 1.2 Treatments available for Osteoarthritis: – There are various ways to cure Osteoarthritis when it is at the initial level, such as: – Exercise and weight loss Bracing Medication Viscosupplementation Nutritional supplements (Duthey, 2015). But when it becomes incurable by exercise and medication, surgical operations must be performed. Surgical procedures include: – Debridement i.e. Smoothening of the cartilage using surgical instruments Marrow Stimulation, a treatment which helps in regrowth of cartilage in the joint (but this process is less reliable) (Treatment Options for Osteoarthritis in the Knee, 2017). Mosaicplasty, a process where the cartilage from some other joint of body is used. But this process h as size limitations (Medical News Today, 2017). Autologous Chondrocyte Implantation, a treatment in which a small part of no-load bearing cartilage is removed from the joint of the patient by Arthroscopy, regrown and multiplied in the laboratory and then implanted back in the body by a procedure called arthrotomy. (Cartilage Repair, 2017) (Ahmed and Hincke, 2010) (Duthey, 2015). Even though the Autologous Chondrocyte Implantation seems effective and easy, it has many disadvantages such as: – The patient’s cartilage sample must be removed by a medical procedure, marked/tagged and treated separately just like blood sample. This treatment requires big Logistics and Supply Chain. It requires a lot of time (approximately 6 weeks) for cells to multiply. Hence, till then the patient will suffer from pain (Peretti et al. 2000). 1.3 Proposed Treatment for Osteoarthritis: –

Gay adoption Essay Example | Topics and Well Written Essays - 1500 words

Gay adoption - Essay Example †). This limited scope of adoption is contrary to the legal rights that the validity of gay marriage protects. If the couple find themselves free to openly love one another, why are the laws of the land preventing them from doing what comes naturally to a married couple? That of starting a family. Admittedly, same sex couples are not biologically capable of impregnating one or the other in order to achieve a naturally formed family. We also must admit that as a society there are still millions of children housed in adoption institutions or foster care systems looking for a good home. Good homes are hard to find these days, even with heterosexual couples. So why not give the same sex couples a try? Why not allow them to adopt a child and prove that they too can be exemplary parents to their children, even though they may not share the same bloodline? These adopted children need loving homes, who is to say that a a same sex home cannot provide that? What exactly are the reasons t hat our society still has inhibitions when it comes to allowing same sex couple to adopt? This paper aims to look at the arguments both for and against same sex adoptions with the full intention of providing factual information that will prove that allowing same sex adoptions will prove beneficial to the child and therefore, should be legally allowed across the United States. Let me begin this discussion by presenting the con side of the argument. These arguments range from psychological in nature, all the way to religious defenses. Whatever the argument presented, these non-supporters of the gay adoption cause do so on the same grounds, they are little informed and truly homophobic in nature which is why they are opposed to the love of a same sex couple being shared with a child who wants nothing more than the same. Politicians such as the United Kingdom's Independence party candidate Winston McKenzie has declared that gay adoption should be likened to child abuse and is a violatio n of a child's human rights. Mr. McKenzi claims that there is an abuse of the child's rights because; â€Å"that child has no opportunity to grow up under normal circumstances... There are people out there who bring up their kids encouraging them to believe they are gay themselves. † (Chorley. Matt â€Å"Allowing Gay Couples to Adopt Is a Form of Child Abuse, Says UKIP Election Candidate). It is important to note that Mr. McKenzie is a Christian with anti-gay sentiments therefore same sex adoption was against his religious beliefs. Aside from religious points of view such as Mr. McKenzie's the cause for gay adoption was not helped by the June 29 news that gay father Frank Lombard sexually molested his 5 year old adopted son. Reports coming from the Associated Press indicate that this is a disturbing trend that is emerging from a scientific literature about gay fathers. According to reports: â€Å"The Arrest Warrant documents that Lombard sodomized one of his two adopted Afr ican-American sons and made the boy give him oral sex on-line† (Cameron, Paul Dr. â€Å"Lombard Demonstrates Why Gays Should Not Be Allowed to Adopt†). The main fear of the psychological community is that children in same sex adopted homes are dangerously exposed to child molestation due to the queer lifestyle of the adopted parents. In the peer-reviewed Psychological Reports journal, Dr. Paul Cameron of the

Case Analysis of Golden Year Village Research Paper

Case Analysis of Golden Year Village - Research Paper Example CCRC or ‘Continuing Care retirement Community’ projects have evolved as standalone industries that meet the growing demands of healthcare issues of people in their post retirement period. The Golden Years Village is a CCRC project that primarily provides multifaceted post retirement healthcare services to elderly population above sixty years of age in Portsmouth, Pennsylvania. The paper would discuss the project as ‘for profit organization’, using SWOT analysis. Key strategic factors of Golden Years Village Strengths GYV has more than 29 years of experience in the area of meeting the healthcare needs of elder population and understands the myriad problems of old age It runs cost effective programs that give residents options of individual services and housing facilities as well as meeting their wider needs of personal requirements of assisted living and personalized nursing. The vast campus of GYV is also equipped with state of the art recreational activitie s which help the residents to de-stress and actively enjoy life. Uses technology to enhance operational efficiency. Despite previous losses, its profitability indicator is better than its rivals. Weakness Due to stringent government rules and regulation, cannot increase prices of its product to meet the increasingly higher cost of healthcare deliverable. The organizational structure is mechanistic and prefers stability and resists change. The centralized power significantly reduces empowered decision making capabilities of employees which adversely impacts performance and efficiency. Does not have strategic market plans for its products and mainly relies on word to mouth publicity as its major market ploy. It lacks financial resources to meet new challenges Opportunities The increasing number of aged population offers huge opportunities to expand its products to suit the growing demands of the people. Threat The major threat is from the new entrants that are ‘for profitâ€℠¢ organizations and who are better equipped to offer customized packages to customers. Wider implications of key strategic factors Golden Years Village is endowed with sprawling area and has expert human competencies that can utilize space and become more creative in their products and services. Ward et al. (1984) claim that 20% of the population is between the age group (60-69) while 65% is above 80 years of age! With increased life expectancy, population of elderly has rapidly grown. Hence there are huge opportunities for GYV to expand its products and services to meet the fast changing preferences of elderly population. The advancing technology has created more awareness amongst aged people and empowered people with myriad options. At the same time, awareness has also resulted in advance planning of post retirement period. GHY therefore should introduce new products that meet the changing requirements of people. People want to be more active and maintain healthy lifestyle. Hence, introducing alternative healthcare imperatives like yoga, meditation, naturopathy etc, would be hugely attractive as they offer holistic healing that takes into consideration the physical, mental and social aspect of the individuals. Ernst et al. (2004) have defined alternative medicine as diagnosis, treatment and/or prevention which complements mainstream by contributing and satisfying a demand that is neither met by convention nor by widening the conceptual frameworks of medicine. It helps people with better sense of wellbeing. Since, CCRC has emerged as an

Marijuana Should Be Legalized for Medicinal Purposes Essay -- Argument

Marijuana Should Be Legalized for Medicinal Purposes How would most Americans react if the law allowed the use of heroin, LSD, or amphetamines for medical purposes? Many of us would react in disbelief mainly because of the effects of these powerful and addictive drugs. However, in Arizona the law permits the use of heroin, LSD, and amphetamines for medicinal purposes, yet the medicinal use of marijuana remains illegal in the United States ("Facts"). Because marijuana is categorized as a Schedule 1 drug under the federal Controlled Substance Act ("Issues"), physicians cannot legally prescribe it. The national debate on the effectiveness of marijuana as medicine is divided between those who advocate marijuana's medicinal value and those who dismiss the claim that marijuana poses any medicinal value. Although many regard the use of medicinal marijuana as a hoax, there is evidence to the contrary that helps to create a substantial argument as to marijuana's ability to provide effective relief from certain symptoms of disease. Patients of t erminal or critical illnesses should be allowed, under the care and supervision of a physician, the option of using marijuana for medicinal purposes. First and foremost, the medical value of marijuana is primarily a means of relief from the symptoms associated with diseases themselves and their treatments, not a cure. Therefore, its therapeutic values are not based on a particular disease, but rather the symptoms such as nausea, vomiting, and anorexia caused by loss of appetite and chronic pain. The exact reason why marijuana relieves such symptoms is not known but most likely lies in its organic composition and ingredients. Marijuana is made up of over 400 organic chemicals, 60 of which are... ...arijuana: the struggle for legalization."

Sample details Pages: 4 Words: 1094 Downloads: 3 Date added: 2019/03/28 Category Literature Essay Level High school Tags: Into The Wild Essay Did you like this example? When we are tired of our society, being close to nature is a very good choice. The protagonist of Into The Wild hates the rules of society and choose to go to the wild. Into The Wild, written by Jon Krakauer, was about Chris McCandless, who took a long trip to explore the wild of Alaska and met many interesting friends on the way. Don’t waste time! Our writers will create an original "Living In The Wild" essay for you Create order Although he finally starved to death in the wilderness, he was very happy on this journey because there were no rules, and there was absolute freedom. Alice Walker said that In nature, nothing is perfect and everything is perfect. Trees can be contorted, bent in weird ways, and theyre still beautiful. In other words, people might think of nature as not perfect because there are fierce predators, insects that contains disease, strange trees, and uncomfortable living environment. However, on the other hand, there are people loving the nature because there was no hustle and bustle of the city and no restriction of rules. There could forget all your worries and do whatever you want. Chris McCandless was one of them. Although many people thought living in the wild is dangerous and uncomfortable, he found it perfect because he could stay away from his family conflicts, the fetters of rules, and enjoying his encounters with new experiences. McCandless had a very complicated family, and the relationship between he and his parents was one of the reasons why he wanted to live alone in the wild. Imagine how an extreme controlling father could get along well with an extravagant independent son. Moreover, his father had other families outside, which violated ethics. Therefore, he chosen to leave the family and live alone in the wild. According to this book, He brooded at length over what he perceived to be his fathers moral shortcoming, the hypocrisy of his parents lifestyle, the tyranny of their conditional love. Eventually, Chris rebelled-and when he finally did, it was with characteristic immoderation. This means that He could not stand his parents anymore and wanted to completely knock them out of his life. Thats why he said that their parents behavior was so irrational, so oppressive, disrespectful an insulting that I finally passed my breaking point. He hated his fathers control and his familys plans for his future. He felt that he was just like a bird in a cage. Thus, he decided to stay away from the family, and he is living into the wild now. Although some people may think that this was not a good idea because there was no one to care for him, it was easy for him to forget the worries that his father caused by his two wives and to stay away from his fathers control over him. Nobody could tie him down here. He could enjoy the freedom brought by nature. Natural disasters are inevitable in nature, but they are opportunities for McCandless to get rid of society. When he was driving in the jungle, car which seemed to be convenient became very heavy. Not only cars but also other modern products had become very useless in the wild. According to this book, Instead of feeling distraught over this turn of events, moreover, McCandless was exhilarated: He saw the flash flood as an opportunity to shed unnecessary baggage.(29) In other words, High-tech products in the wild had become a fetter to McCandless. Thus, he used the flood to throw away all those tools, leaving only necessary supplies. It was also a symbol of his desire to break away from society and get close to nature. Natural disasters that frighten others become a way for him to fulfill his dream. Without the bondage of these things, he could enjoy the endless freedom brought to him by nature. Money in society is very important. People think nature is not perfect because they cannot get money from wild. However, McCandless doesnt care about money. Money was a fetter to him. According to this book, Then, in a gesture that would have done both Thoreau and Tolstoy proud, he arranged all his paper currently in a pile on the sand-a pathetic little stack of ones and fives and twenties-and put a match to it. One hundred twenty-three dollars in legal tender was promptly reduced to ash and smoke. In other words, in nature he could get everything he wanted. Money became useless here. He didnt want money to disturb his natural time. Some people see nature as dangerous, but for McCandless, nature is very beautiful because he feels tried of social hypocrisy and yearn for a simple life. According to this book, McCandless was stirred by the austerity of landscape, by its saline beauty. The desert sharpened the sweet ache of his longing, amplified it, gave shape to it in sere geology and clean slant of light. A big temperature difference and an extreme lack of water made desert very dangerous in peoples minds. However, he was attracted to the saline land. Here, massive dunes stretched in every direction as far as the eye could see, for him, it was beautiful. It was this feeling of no restraint that moved him and made him feel comfortable. Life in the wild required great care every day, but McCandless was deeply attracted to the life where he had new experiences every day. According to this book, If you want to get more out of life, you must lose your inclination for monotonous security and adopt a helter-skelter style of life that will at first appear to you to be crazy. But once you become accustomed to such a life you will see its full meaning and its incredible beauty. In other words, he thought the joy of life is in experiencing something new every day. And nature satisfied his idea. In the wild, McCandless never knew what would happen next second. Others thought it was irrational to live alone in the wild because it was hard to have a comfortable and fixed place to live. He thought that the wandering life in the wild would be a surprise every day. Thats why he said that Dont settle down and sit in one place. Move around, be nomadic, make each day a new horizon. It was this novelty that made him willing to live in the wild to enrich his personal experience. To summarize, living in the wild made him forget his family problems and social rules, enjoy his freedom and enrich his experience, which made him think the nature that others fear and awe was very beautiful.
