To determine

To describe: The basic characteristics that define an independent-measures, or a between-subjects, research study.

Answer to Problem 1P

It uses a separate sample for each of the treatments or populations being compared

Explanation of Solution

An independent measures design is the one in which different participants are used in each condition of the independent variable. Different participants are used for the two groups i.e. every participant is only subjected to a single treatment.

Since independent measure design uses two distinct populations (and population means), hence, each of these have their own sample mean and variances.

ons 12. A sociologist hypothesizes that the crime rate is higher in areas with higher poverty rate and lower median income. She col- lects data on the crime rate (crimes per 100,000 residents), the poverty rate (in %), and the median income (in $1,000s) from 41 New England cities. A portion of the regression results is shown in the following table.
