What you will submit for Task 2: Paired samples t test output for the study below.
You want to study the effects of caffeine on memory and you have 30 participants. You decide to do a within-subjects design using a pre-test/post-test. So you give your subjects a fake caffeine pill (placebo) and some time for the pill to “take effect”. Then you give them some time to study a list of 10 words and test them on recall. You then give them a break to rest their mind, and subsequently you give your same subjects a real caffeine pill, give some time for the pill to take effect, give them the same amount of time to study a similar but different list of 10 words and test them for recall.
Column 1 below contains the scores of your subjects after they took the caffeine pill (post-test)
Column 2 below contains the scores of your subjects with the fake caffeine pill (placebo). (pre-test)

III. Task 3 – Independent Samples t Test
What you will submit for Task 3: Independent samples t test output for the study below.
You want to study the effects of caffeine on memory and you have 60 participants. You decide to do a between-subjects design using simple random assignment. So you randomly assign subjects to two groups: Caffeine pill and Placebo pill. So you give your subjects the pill and some time for the pill to take effect. Then you give both groups the same amount of time to study the same list of 10 words and then test them on recall.
Column 1 contains the scores from both groups. The first 30 scores are from the caffeine group and the second 30 scores are from the placebo group.
Column 2 contains thirty “1”s and thirty “2”s. The 1s will be your caffeine group and the 2s will be your placebo group.

IV. Task 4 – One way Analysis of Variance (ANOVA)
What you will submit for Task 4: One way ANOVA test output for the study below.
You want to test the effects of Caffeine and a new drug called “Limitless” (a PKR Inhibitor) on memory and you have 90 participants. So you decide to split them up into three groups using simple random assignment. Each group will receive a different pill (Placebo, Caffeine, Limitless) and you give them the same amount of time for the pill to take effect. You then give each group the same list of 10 words and give them the same amount of time to study the list of words and you test them for recall.
Column 1 contains the scores all three groups. The first 30 scores are from the Limitless group, the second 30 scores are from the caffeine group and the last 30 scores are from the placebo group.
Column 2 contains thirty “1”s and thirty “2”s and thirty “3”s. The 1s will be your Limitless group, the 2s will be your caffeine group and the 3s will be your placebo group.
