Chapter 10, Problem 1P
Describe the basic characteristics that define an independent-measures, or a between-subjects, research study.
Expert Solution & Answer
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.
