You want to study the effect of a new Drug A to treat type 2 diabetes vs. the standard of care in a randomized controlled trial. You include 1000 subjects (500 in each arm). You response is the glucose level in mmoll. What type of statistical test would you use? O A. Fisher Exact Test B. One-way ANOVA 0 C. Chi-square D. Two-way ANOVA O E, Independent T-test
If you had an additional group (n=500) and you gave them a placebo pill so that you end up with 3 groups. What type of statistical test would you use? A. One-way ANOVA B. Fisher's Exact Test C. Two-way ANOVA D. AnCova E. Chi-square
You then realized that there were baseline differences among the 3 groups so that their diet, smoking, and physical activity habits were different. What type of statistical test would you use? A. Chi-square B. One-way ANOVA C. Two-way ANOVA D. Fisher's exact test E. AnCova

2. A study was conducted to test the effect of a new drug (Clofibrate) on reducing the coronary death compared to placebo. Patients were randomized into two groups at 1:2 ratio. Of 1065 subjects in the treatment group, 194 died at 5 years, whereas 523 of 2695 subjects in the placebo group died at 5 years. Answer these questions: a) what is the study design? b) generate a 2 by 2 table, c) calculate the crude mortality rates for both...
You want to determine if salary is affected by gender and whether the employee has a graduate degree or not (taken together). The correct statistical technique/test would be: Chi-square Correlation One-tailed ttest Two-tailed ttest Simple linear regression Multiple regression Logistic regression Dummy variable regression ANOVA One-way ANOVA
The Dean analyzed 100 randomly selected student opinion survey answers to assess whether students' response to one rating question, ""The instructor created a course environment conducive to my learning"", was independent of the students' rating of another question ""Overall, my learning experience in this course was ..."". Each item was measured on a 5-point scale. What test would be used? Two-sample t-test. Paired t-test. Wilcoxon rank sum test (U test). Sign test. One-way ANOVA. One-way repeated measures ANOVA. Kruskal-Wallis test....
The primary factor that determines the statistical test students should use is the number of independent and dependent variables. True or False When investigating the relationship between two or more quantitative variables, chi-square is the appropriate test.True or False The Pearson correlation coefficient measures the association between two quantitative variables, distinguishing between the independent and dependent variables.True or False Multiple regression is used when there are several dependent variables and one independent quantitative variable.True or False When testing for the...
Using the South University Online Library, the Internet, and your text readings, research the following statistical topics: Contingency tables The chi-square Fisher's exact test (FET) On the basis of your research, respond to the following: Find and state a definition of a contingency table that you feel is easy to understand. In your own words, explain what contingency tables are and what they are used for. Explain what type of data is displayed in contingency tables. Explain how contingency tables...
Question about ANOVA. I have a hypothetical scenario. So we're conducting a study. In the study there are four types of treatments (three are drugs, one is placebo), and two types of people. So 8 groups of people all together, right? Subjects are measured at baseline and then at another point say in three months or so. My question is does time also count as an IV? So the IVs would be type of drug, type of person, and time?...
