A researcher is studying the effects of time delay on memory. She recruits a group of participants, and each participant undergoes three conditions. In the first condition, the participants are presented with a list of numbers and must wait 10 seconds before recalling those numbers. In the second condition, the delay is 30 s instead of 10 s; in the third condition, the delay is a full minute. The order in which a participant undergoes these three conditions is randomized. The null hypothesis is that there is no difference in participant's recall abilities in these three conditions. The most appropriate test to analyze the results would be:

Group of answer choices

a. A one-sample t-test

b. An unpaired two-sample t-test

c. A paired two-sample t-test

d. A one-way ANOVA

e. A repeated-measures ANOVA

f. A two-way ANOVA

g. A Pearson's correlation test

h. A chi square test for goodness of fit

i. A chi square test for independence
