site.)I. Task 1 – One Sample t TestWhat you will submit for Task 1: One sample t test output
for the study below.You want to study the effects of caffeine on memory and you have 30
subjects who are willing to participate in your study. So you give your subjects a caffeine
pill, give some time for the pill to take effect and then give them some time to study a list of
10 words and then test them for recall. You have done this memory test countless times
with past subjects under the same conditions (but these subjects were not-caffeinated) and
you found that their mean recall was (μ = 6) but you did not collect the standard
deviation. So in this experiment you know the population mean (μ = 6) but do not know the
population standard deviation. Run a one sample t test with the data below to see if caffeine
improves memory recall.Column 1 =1010999888887776610109998888877766Start a new
file in SPSS.Enter the data into Column 1In Variable View: Name your variable (CAFFEINE
for Column 1), Specify Type (Numeric), Specify the type of Measure (Scale).From the
Analyze menu at the top, choose Compare MeansChoose One-Sample t test from the list of
tests.In the Variable window, highlight your variable and then use the arrow to move it into
the Test Variable box.Enter your known population mean (μ = 6) into the Test Value
box.Click OK; your statistics will appear in the Output window.There are many ways to save
your output. A nifty function that I like is to use the Export function. This exports the data
to an MS word doc which allows you to manipulate the data quite easily and put into one
document. To do this, in your data output, choose the icon that represents “Export” (or
from the Files Section choose “Export”) and for “Objects to Export” select “All Visible” and
then voila’! Another way is to copy and paste the outputs and put them into a word
document. To do this, I left click on the t test output and then right click and “copy”, and
then I go to my word document and right click and press “paste”. There are other ways to
save your output into one document. Feel free to do whatever works for you.II. Task 2 –
Paired Samples t TestWhat 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

Variable box.Click OK; your statistics will appear in the Output window.There are many
ways to save your output. A nifty function that I like is to use the Export function. This

you.III. Task 3 – Independent Samples t TestWhat 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.Column 1

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.Column 1
