1.**Similar
to ***t-test*** Ð except IV has 2 or more levels
**

2.**One-Way
**

n1 IV analyzed and 1
DV measured

nH0: population means are all equal (H0: µ1 = µ2 = µ3)

nH1: population means are NOT equal (µ1 µ2 µ3)

nTreatment Ð may have
more than 2 levels

3.**Hypothesis
testing**

nH0 (null) and
H1 (alternate) hypotheses are stated (Assume H0 is
true)

nSampling
distribution Ð *t *or *F*

nGather data and
calculate F value

nCompare calculated *F* to table
value and Interpret results

4.**F
distribution**

nF is a sampling
distribution (just as *t* distribution is)

nRatio Ð
treatment/between groups variation to within group variation

¤B - between groups Ð do groups differ due to
treatment

¤W or E within (error) Ð unbiased estimate of variability
in same group

¤B > W reject Ho (treatment had effect)

¤Small variability (F=1.00) Ð keep H0, large var (F > 1.00) Ð reject H0
