3. Column titles in a table should describe which of the following? A) The independent variable B) The dependent variable C) The covariate variable 4. Which graph would be most useful in determining the change in two variables over time? A) A histogram B) A bar chart C) A line chart D) A flow chart D) The grouping variable 5. Which type of statistical information or graph would be most helpful in determining whether the baseline characteristics of a study group are well balanced? A) A bar chart B) Descriptive statics C) A box-whisker plot D) A flow chart True/False 1. True or False? Using a 95% confidence interval to describe an odds ratio allows other researchers to determine if the results were statistically significant because a statistically significant odds ratio confidence interval will not include the number 1. 2. True or False? The r2 value and a least squares regression line can be an excellent way to demonstrate the degree of correlation between two variables, and the type of association between the two variables. 3. True or False? Box-whisker plots are useful tools in comparing the mean and the distribution of two or more variables broken down into different categories. 4. True or False? Variable names and units of measurement should be specified clearly and accurately. 5. True or False? Good tables have clear and concise titles.
