What is one reason that the researchers used a one-way between-groups ANOVAs (one for likeability and one for perceived sincerity) for this experiment?

a. Each analysis used data from more than one-time point, perceptions of bragging, humblebragging, and complaining were all assessed before the experiment before the experiment for comparison purposes.

b. Each analysis compared a single sample with a known population mean.

c. There are 3 independent variables in each analysis; humblebrag, brag, complain.

d. For both analyses, there was a scale dependent variable-either likeability or perceived sincerity rating.
