question 15 (1 point)
the following diagram represents
independent samples
paired samples
one sample
neither answer is correct
more information is needed to determine which t - test to use

Explanation:

In a paired - samples t - test, the same group of participants is measured twice (e.g., before and after an intervention). In an independent - samples t - test, two different, unrelated groups of participants are compared. The diagram shows two distinct groups (not the same individuals measured twice), so it represents independent samples.

Answer:

independent samples
