STEP 1: State the hypotheses and select an alpha level.
H0: µ1 = µ2 = µ3 (There is no treatment effect.)
H1: At least one of the treatment means is different.
We use α = .05

STEP 2: Locate the critical region.

df total = N - 1 =

df between = k - 1 = (Numerator)

df within = N – k = (Denominator)

look up in the f table: df = Numerator, Denominator, Critical region =

STEP 3: Compute the F-ratio.

SS total = ΣX^2-G^2/N =

SS within = ΣSS inside each treatment =

SSbetween = SStotal – SSwithin
=
Calculation of mean squares
MS between=(SS between)/(f between)
MS within=(SS within)/(f within)

Calculation of F.

F=(MS between)/(MS within)
=
STEP 4 : MAKE A DECISION

The following data were obtained from an indepen-
dent-measures research study comparing three treat-
ment conditions. Use an ANOVA with a = .05
to determine whether there are any significant mean
differences among the treatments.
