ANALYSIS OF VARIANCE (ANOVA)
A STATISTICAL TECHNIQUE FOR TESTING FOR DIFFERENCES IN THE MEANS OF SEVERAL GROUPS
ONE WAY ANOVA
AN ANALYSIS OF VARIANCE WHEREIN THE GROUPS ARE DEFINED ON ONLY ONE INDEPENDENT VARIABLE
MS within (MS error)
VARIABILITY AMONG SUBJECTS IN THE SAME TREATMENT GROUP
MS between groups (MS groups)
VARIABILITY AMONG GROUP MEANS
SUM OF SQUARES
THE SUM OF THE SQUARED DEVIATIONS AROUND SOME POINT (USUALLY A MEAN OR PREDICTED VALUE)
SS total
THE SUM OF SQUARED DEVIATIONS OF ALL OF THE SCORES, REGARDLESS OF GROUP MEMBERSHIP
SS groups
THE SUM OF SQUARED DEVIATIONS OF THE GROUP MEANS FROM THE GRAND MEAN, MULTIPLIED BY NUMBERED OF OBSERVATIONS
SS errors
THE SUM OF SQUARED RESIDUALS OR THE SUM OF THE SQUARED DEVIATIONS WITHIN EACH GROUP
DF total
DEGREES OF FREEDOM ASSOCIATED WITH SStotal EQUAL TO N-1
DF group
DEGREES OF FREEDOM ASSOCIATED WITH SSgroup EQUAL TO K-1
DF error
DEGREES OF FREEDOM ASSOCIATED WITH SSerror EQUAL TO K(N-1)
F STATISTIC
THE RATIO OF MSgroup to MSerror
MULTIPLE COMPARISON TECHNIQUES
TECHNIQUES FOR MAKING COMPARISONS BETWEEN TWO OR MORE GROUP MEANS SUBSEQUENT TO ANALYSIS OF VARIANCE
PROTECTED T (LEAST SIGNIFICANT DIFFERENCE TEST)
A TECHNIQUE IN WHICH WE RUN T TESTS BETWEEN PAIRS OF MEANS ONLY IF THE ANALYSIS OF VARIANCE WAS SIGNIFICANT
FAMILY WISE ERROR RATE
THE PROBABILITY THAT A FAMILY OF COMPARISONS CONTAINS AT LEAST ONE TYPE I ERROR
BONFERRONI PROCEDURE
A MULTIPLE COMPARISONS PROCEDURE IN WHICH THE FAMILYWISE ERROR RATE IS DIVIDED BY THE NUMBER OF COMPARISONS
TUKEY PROCEDURE
A MULTIPLE COMPARISONS PROCEDURE DESIGNED TO HOLD THE FAMILYWISE ERROR RATE AT ALPHA FOR A SET OF COMPARISONS
MAGNITUDE EFFECT
A MEASURE OF THE DEGREE TO WHICH VARIABILITY AMONG OBSERVATIONS CAN BE ATTRIBUTED TO TREATMENTS
N2 (ETA SQUARED)
A MEASURE OF THE MAGNIFIED OF EFFECT
W2 (OMEGA SQUARED)
A LESS BIASED MEASURE OF THE MAGNITUDE OF EFFECT
