- Distinguish between observational and experimental types of studies?arrow_forwardYou are doing research with people who are homeless. You want to be able to identify those who are depressed so that you can refer them to treatment. You use a depression-screening tool called the Beck Depression Inventory (BDI), created by Dr. Aaron T. Beck. It is a widely used 21-item multiple-choice self-report inventory. Higher scores indicate higher levels of depression. Because being homeless is stressful, you decide to use z- scores so that you can identify those people who are at least one standard deviation more depressed than the typical person who is homeless. Based on the testing of 50 people, the average score on the BDI in your sample is 14 with a standard deviation of 2. The table that follows consists of the scores of five people that you tested who sleep in the same alcove at a shelter. Use the dropdown menus to complete the third column of the table by selecting the z-score relative to your sample that corresponds to the participants' BDI score.

One common area of concern for auto insurance companies is the risk involved when offering policies to younger, less experienced drivers. The U.S. Department of Transportation recently conducted a study in which it analyzed the relationship between 1) the number of fatal accidents per 1000 licenses, and 2) the percentage of licensed drivers under the age of 21 in a sample of 42 cities. Your first step in the analysis is to construct a scatterplot of the data. FIGURE.
