groups of data.
Within-Group - values obtained from one group (factor level)
F-Distribution - The distribution used for determining the significance
in ANOVA.
Sum of Squared Deviations - A quantity that is obtained by squaring and
adding the differences between a group of values and their
mean. SUM((X¡ - mean)²)
Eta Squared - the Correlation Ratio also known as R², the
Proportion of Variance Accounted For.
Independent Variable - A variable that is manipulated by the researcher.
Factor - One of the independent variables.
