1 Question one
The first question selected was as follows; What type of statistical analysis should I use to compare difference in mean body weight for eight different groups?
The question central theme was related to statistical analysis and specifically enquired about the comparison in the means of body weights for eight different groups. The question had been posted on the ReaserchGate discussion forum board by Abdulsalam Halboob from the Jordan University of Science and Technology (Halboob, 2014). Looking at the thread, the question was answered by 48 people all from different academic professions, there were 19 followers of the discussions and 1800 persons who visited the site had viewed the question and the threads. The discussion took place between September 22nd of 2014 when the question was posted the discussion board and October 20th 2014, when the last respondent posted their answer (Halboob, 2014).
1.1 Opinions of the discussion
1.2 Method to use in analysis
Following through the threads of the answers given to the question, it is clear that most of the respondents understood what Abdulsalam Halboob, was enquiring from his question. As such they offered their answers giving reasons as to why the methods they suggested would best give the desired results. However it is also good to mention that some of the people that commented on the thread also wanted more information, such as, the core dependent, independent variables and characteristics of the groups. For example, Richard Donald from Cardiff University on 22nd September of 2014, wanted clarification on what Abdulsalam Halboob wanted to know, relative to the differences between the groups. Most of the respondent suggested that using ANOVA would the best methods to show the differences between the groups. For example Jiancheng Jiang even offered the mathematical fomular that Abdulsalam Halboob, could apply in his analysis using the ANOVA method (Halboob, 2014).
1.3 Areas of Emphasis
Much of the emphasis of the relative to the answers posted, were hinged on the applicability of the ANOVA methods of analysis. According to most of the respondents, the methods would be the best methods as it would easily give the differences between the groups as Abdulsalam Halboob had asked. However, part of the group also felt that it was crucial that the hypothesis is revised otherwise the ANOVA method may not the best answers or at least conclusive answers (Halboob, 2014). Other respondents felt that the suggested ANOVA method would not give the desired results and suggested other methods such as the Kruskal-Wallis method. Some even suggested both ANOVA and the Kruskal-Wallis methods to Abdulsalam Halboob.
Some of the respondents also offered links to books, posts and articles online that would best help Abdulsalam Halboob understand statistics and how to choose his hypothesis, the method and how to interpret the results now and in future (Halboob, 2014). While some of the respondents mentioned the use of the T-test, some others were quick to point out that this test cannot be used in this case as it is only used when comparing means between two groups only. The normality theme also comes up as respon...
