In order to calculate the F-statistic for our sample, we need a few pieces of
information:
We need sample sizes:
n in-person
and
n remote-asynchronous
and
n remote-synchronous
We need group means:
x̄ in-person
and
x̄ remote-asynchronous
and
x̄ remote-synchronous
We need group standard deviations: s in-person
and s remote-asynchronous
and
s remote-synchronous
-
With these six values, we can calculate our test
statistic, F, as well as figure out our
df and effect size, as
dfB= k - 1, and
dfW= N - k, and
η^2=SSB/S
