Final answer:
The researcher reported an F-ratio with df = 2, 24 for a repeated measures ANOVA. There were 2 conditions in the experiment and 24 total subjects.
Step-by-step explanation:
The researcher reported an F-ratio with df = 2, 24 for a repeated measures ANOVA. The df values represent the degrees of freedom for the F-ratio calculation. In this case, df = 2 means there were 2 conditions in the experiment, and df = 24 means there were 24 total subjects.
