A research study measures the effect of age on the average driving speed by selecting a sample of teenage drivers and a sample of drivers between the ages of 20 and 25. Why is this an example of an independent-measures design?

This is an example because there is one measure being taken for two non-overlapping samples.

Step-by-step explanation:

An independent-measures design can also be expressed as a between-subjects design. In the independent-measures design, there are two independent samples that are compared to one another.

The following are the examples that would represent independent measures:

The statistically significant difference can be noted by measuring the average number of traffic tickets among men and women.

A sample of 10-year-olds is compared with a sample of 18-year-olds to measure whether age has an effect on the amount of time an individual can hold his breath under water.
