When you examine data statistically, how many variables do you examine at one time in the descriptive study? Is this different for the explanatory type of study? Explain.
What will be an ideal response?
Ans: When you examine data in descriptive research, you are examining one variable at a time, such as the mean age or the proportion of people who are female. You are not examining the relationship between variables so you do not examine more than one variable at a time. The explanatory type of study, however, has the purpose of explaining one variable by examining its relationship with another variable. Therefore, you are examining more than one variable when you engage in the analysis of data for the explanatory study.
