Perform Related and Independent t samples in Jasp-Must show calculations for both worksheets!

Name:

A zombie researcher is interested in studying attitudes towards zombies. The researcher collects attitude ratings on a sample of 30 participants (ZOMB1), then has the participants complete a sensitivity training course aimed at increasing their attitude towards zombies. The 30 participants are then given the attitude survey again after completing the training (ZOMB2).

Complete this worksheet to test the hypothesis that the sensitivity training significantly increases attitudes towards zombies. You will need to perform a related samples t test using the summary data below and by using JASP.

ZOMB1	ZOMB2
N = 30
D = -76
D2 = 224
= -2.533

1. Does the sensitivity training significantly increase attitudes towards zombies? (1 point)

a. Hypotheses:

i. Null hypothesis:

ii. Alternative Hypothesis:

b. Criterion (1 point)

i. One tailed or two tailed?

ii. df =

iii. Critical value at .05 level:

c. Calculate: tobt =

Show formula and computations (using summary statistics from table above): (4 points)

d. Determine significance (2 points)

i. Reject or fail to reject the null hypothesis:

ii. If significant describe finding:

2. Perform the same related samples t-test using JASP. Include the location parameter, effect size statistic, descriptives, and descriptives plots. Copy and paste the output from the JASP test below. (4 points)
