HSD analysis of variance
The parametric procedure for determining whether significant differences exist in an experiment containing two or more sample means; abbreviated ANOVA
ANOVA
Abbreviation of analysis of variance
between-subjects ANOVA
The type of ANOVA that is performed when a study involves between-subjects factors
between-subjects factor
An independent variable that is studied using independent samples in all conditions
error variance
The inherent variability within a population, estimated in ANOVA by the mean square within groups
eta squared
The proportion of variance in the dependent variable that is accounted for by changing the levels of a factor, and thus a measurement of effect size
experiment-wise error rate
The probability of making a Type I error when comparing all means in an experiment
factor
In ANOVA, an independent variable
F-distribution
The sampling distribution of all possible values of F that occur when the null hypothesis is true and all conditions represent on population
Fisher’s protected t-test
The post hoc procedure performed with ANOVA to compare means from a factor in which all levels do not have equal ns
F-ratio
In ANOVA, the ration of the mean square between groups to the mean square within groups
level
In ANOVA, each condition of the factor (independent variable)
mean square between groups
In ANOVA, the variability in scores that occurs between the levels in a factor or the cells in an interaction
mean square within groups
In ANOVA, the variability in scores that occurs in the conditions, or cells
multivariate statistics
Procedures applied to a study that measures two or more dependent variables
one-way ANOVA
The analysis of variance performed when an experiment has only one independent variable
post hoc comparisons
In ANOVA, statistical procedures used to compare all possible pairs of sample means in a significant effect, to determine which means differ significantly from each other
sum of squares
The sum of the squared deviations of a set of scores around the mean of those scores
treatment
The conditions of the independent variable
treatment effect
The result of changing the conditions of an independent variable so that different populations of scores having different p s are produced
treatment variance
In ANOVA, the variability between scores from different populations that would be created by the different levels of a factor
Tukey’s HSD multiple comparisons test
The post hoc procedure performed with ANOVA to compare means from a factor in which all levels have equal n
univariate statistics
Procedures applied to a study that measures only one dependent variable
within-subjects ANOVA
In ANOVA, the variability in scores that occurs in the conditions or cells
