Part 1: Use JAMOVI to conduct the ANOVA by copying and pasting the data into the app.
Remember that JAMOVI treats each row as a single participant (Hint - You’ll have two columns of data: DV_lastname and GROUP_lastname)

Part 2: Confirm JAMOVI’s conclusions by conducting the same ANOVA manually.

STEP 5:
Part 3: Calculate h2
for these data and explain what this value means.
Part 4: Conduct Tukey’s
post hoc
tests, using the method described in class.
STEP 1: What is the HSD value?
STEP 2: Create the table of differences. Note that means should be arranged from largest to smallest (i.e. MEAN 1 is the largest of the three means, MEAN 2 is the second largest mean, and MEAN 3 is the smallest of the three means), and that you should only add those differences that are absolutely required (i.e. don’t do more work than you have to). Highlight the differences that are HSD.
