For results that included four groups of with a total number of 250 participants, what would the appropriate degree of freedom be?
Homework Answers
solution
given that
n =250
Degrees of freedom = df = n - 1 = 250- 1 = 249
df=249

Four groups of college students underwent a sleep deprivation
study. There were 6 participants per condition. They had been
deprived of sleep for 0, 6, 12, or 24 hours. Afterwards, a memory
test was given. An ANOVA was conducted in Microsoft Excel and the
results are given in the table below. Follow-up this ANOVA with a
post hoc test (α= .01) to determine which groups differed.
