Hlt 362 Exercise 36 Essay - 839 Words

Exercise 36 1. The researchers found a significant difference between the two groups (control and treatment) for change in mobility of the women with osteoarthritis (OA) over 12 weeks with the results of F(1, 22) = 9.619, p = 0.005. Discuss each aspect of these results. The F-value is high enough at the 5% level of significance to suggest a significant difference between the control and treatment groups. The p-value 0.005 lt; 0.05 hence this suggests a rejection of the null hypothesis, meaning that the control and treatment groups are found to be different. 2. State the null hypothesis for the Baird and Sands (2004) study that focuses on the effect of the GI with PMR treatment on patients’ mobility level. Should the null†¦show more content†¦6. Can ANOVA be used to test proposed relationships or predicted correlations between variables in a single group? Provide a rationale for your answer. Yes this is one of the main functions of the ANOVA -- to say whether or not there exists a relationship or correlation between groups. Normally, if the p-value is less than the significance level there is a difference between the groups, and if the p-value is larger than the significance level there is no difference between the groups. 7. If a study had a result of F(2, 147) = 4.56, p = 0.003, how many groups were in the study, and what was the sample size? If K = number of groups in the study, and df = K - 1 then K = df+1 = 2+1 = 3. So there are 3 groups in the study. There are N - K number of participants so N = K+147 = 3+147 = 150 participants. 8. The researchers state that the sample for their study was 28 women with a diagnosis of OA, and that 18 were randomly assigned to the intervention group and 10 were randomly assigned to the control group. Discuss the study strengths and/or weaknesses in this statement. In my opinion, I would like to see a larger sample size. But I agree with the choice to put more participants into the intervention group rather than the control group. That is because I would be more interested in the results from the intervention group so a larger sample is appropriate, but there is still enough in the control group to playShow MoreRelatedEssay on Exercise 11 161073 Words   |  5 PagesName:SALYYOHANNAN________________________________________ Class HLT-362V______________________ Date:11/16/2014______________________________________________ EXERCISE-11 1) What demographic variables were measured at least at the interval level of measurement Education is measured at the interval scales because the data is measured on specific intervals, and grades of education. 2) What statistics were used to describe the length of labor in this study?

Analysis Of Othello By William Shakespeare - 816 Words

Tristan Le Mrs. Bell Eng. 1 Pre-I.B. 05 April 2015 Self-Confidence In the book, Othello, by William Shakespeare, the author expresses that without self-confidence a person cannot truly grow emotionally. He shows this theme throughout the book by giving Othello, the main character, the trait of low self-confidence. After the main antagonist Iago pushes Othello to his limits this trait turns out to be fatal and leads to the downfall and death of Othello. A small contribution to his low self-confidence is race, because he is black he doesn’t fit into his society. As a high ranking general in the Venetian army, he is very well respected for his military prowess, Towards the beginning of the book, Othello is called racial slurs by Iago such†¦show more content†¦The most prominent cause of Othello’s low self-confidence is displayed in his uncertainty in his love for Desdemona. At the beginning of the book, Othello was quite self-confident about himself saying that, â€Å"I won his daughter† (1.3.111). He is obviously so conf ident that he is able to say it outright in front of Brabantio; he even goes as far as saying, â€Å"Send for the lady to the Sagittary and let her speak of me before her father† (1.3.135-36), as if he knows for certain that she will confess to him as well. He also exclaims later in the book that, â€Å"I had been happy if the general camp, pioneers and all, had tasted her sweet body† (3.3.397-98), referring to the fact that his self-confidence was so high that it wouldn’t matter to him if everybody in the camp had sex with her; he would still know that she loves him. As the story moves on it comes to show that Othello gradually loses self-confidence. In Act 3 Scene 3, Iago first plants his seeds of doubt into Othello through lies that he tells him. He tries to paint the picture that Desdemona and Cassio are having affairs even though he has no proof to show for it. After Othello shows that he doesn’t buy into this, Iago adds in that, â€Å"She did decei ve her father, marrying you† (3.3.238), trying to hint that if she could trick her own father that she could fool him also. This leads to Othello stating, â€Å"Set on thy wife to observe† (3.3.281), meaning that he wants

Early Civilizations HUMA215-1205A-32 Topics in Cultural Studies Unit 1 Discussion Board Shannon Sullivan There were many different forces that have contributed to the cultural makeup of early civilization. The beginning of human culture predates back to thousands of years which can be seen through evidence that has been discovered. This evidence that was left behind by the earliest of humans is found by cave paintings that helped to understand how these prehistoric individuals lived and survived in their everyday life. We will write a custom essay sample on Early Civilizations or any similar topic only for you Order Now One aspect that contributed to the cultural makeup is from geographical areas from where these early humans lived. The geographical region determined what their main focus was when it came to agriculture, hunting, trade and religion. The availability of these natural resources would affect the kinds of houses they lived in, the types of weapons and tools they used, the food they ate and the type of containers they used to store food and supplies (Trigger, 2003). A number of social issues occurred because of this cultural makeup. These issues were the cause of war and conflicts between many of these early humans. One of the factors that caused social problems was a result of different spiritual and religious beliefs. Others factors were political, economic and the development of one’s social class. Since early civilization started, humans lived successfully in small hunting and gathering tribes. This was the dominant way of life until agriculture began to gradually replace hunting and gathering of necessities such as food, clothing and homes which was some of the main cultural influences on early civilizations (All World History for Us, n. d. ). Revisionist history can be bad. The problem with revisionist history is that it usually is written by someone who has a curriculum that they want to publicize. Most of this comes from inaccurate information from an unbiased viewpoint. Their minds tend to be made up prior to looking at the facts. This results in choosing facts that support their viewpoint and ignoring facts that disprove their predetermined ideas. Another problem with revisionist history is that it tends to judge people, cultures and experiences in the past by the values, ethics and morals of today’s society. People in the past lived with the knowledge, superstitions, values and ethics of their day and should be studied to find the correct information. The only good thing about revisionist history is when the correct information has been given. All World History for Us. (n. d. ). Farming and the Emergence of Complex Societies.
