Your goal is to analyze the following question. Did the encoding task affect participants' memory performance? Specifically, did their hit rate (i.e., how frequently they correctly recognized previously studied words) differ between strong items (HR_Strong) and weak items (HR_Weak)?

What is the appropriate statistical test to use in this situation?

Group of answer choices

a. Paired samples t test

b. One sample t test

c. independent samples t test

What is justification for the answer you provided above?

Group of answer choices

a. Same sample of people who are tested at two conditions.

b. Two different groups are being compared.

c. One group (sample) is being compared to a population

Conduct the appropriate test and identify the obtained test statistic from the options shown.

Group of answer choices

t = 6.36

t = 4.34

t = 2.53

Was there a significant difference in memory between strong items and weak items? What would be the decision?

Group of answer choices

Yes, significant difference because p < .001 ( p < .05) so we reject the null hypothesis.

No, there was no significant difference, so we fail to reject the null hypothesis.
