Within-Groups (Repeated Measures) ANOVA

3. A researcher is interested in how movies affect our physical state. She has participants watch movies from three different genres and measures their average heart beats per minute (BPM) while watching the movies. The data is as follows:

participant	horror	romantic comedy	action
A	55	32	57
B	50	35	56
C	58	39	56
D	57	33	58
E	53	37	52

a. Who are the groups being tested:

b. State the null and research hypotheses:
c.

SOURCE	SS	DF	MS	F
between
subjects
within
total

What are the means for each group?
What are the means for each participant?
What is the grand mean?
What is DF between? (number of groups -1)
What is DF subjects? (number of participants -1)
What is DF within? (DFbetween times DFsubjects)
What is DF total? (DFbetween + DFsubjects + DFwithin)
Complete the table according to your notes
d. What is the critical value?
e. What decision do we make?
