Answer:

a. A repeated-measures analysis of variance            

Step-by-step explanation:

Repeated-measures analysis of variance: In statistics or research methods, the term "repeated-measures analysis of variance" is also denoted as "repeated-measures ANOVA", and is described as one of the members of the "ANOVA family". However, each ANOVAs tends to compare one or more than one "mean scores" with each other and is considered as tests associated with the difference in different mean scores. Therefore, a "repeated-measures ANOVA" consists of at least one "dependent variable" that encompasses more than one "observation".

In the question above, the given statement represents a repeated-measures of analysis of variance.
