F Distribution Tables The F distribution is a right-skewed distribution used most commonly in Analysis of Variance (see ANOVA/MANOVA).

Therefore, the F-value for the main effect of drink (and its interaction with the between-group variable gender) does not need to be corrected for violations of sphericity (see last handout).

The mean squares are the key term in classical ANOVA. They are variances, calculated by dividing the between- and within-group sum of squares by the appropriate number of degrees of freedom. In Table 1, Mb represents the between-group MS term (sometimes denoted M1) and Mw represents the within-group MS term (sometimes denoted M0).

ANOVA design, the term factor is a synonym of independent variable. Therefore, “Type of Smile” is the factor in this experiment. Since four types of smiles were compared, the factor “Type of Smile” has four levels. An ANOVA conducted on a design in which there is only one factor is called a one-way ANOVA. If an experiment has two ...

The analysis of variance (ANOVA) is a hypothesis-testing technique used to test the claim that three or more populations (or treatment) means are equal by examining the variances of samples that are taken. This is an extension of the two independent samples t-test. ANOVA is based on comparing the variance (or variation) between the data samples ...

Interaction effects represent the combined effects of factors on the dependent measure. When an interaction effect is present, the impact of one factor depends on the level of the other factor. Part of the power of ANOVA is the ability to estimate and test interaction effects. As Pedhazur and Schmelkin note, the idea that multiple effects ...

One way is to use the alpha level (the a priori criterion for the probablility of falsely rejecting your null hypothesis), which is typically .05 or .01. Example: F(1, 24) = 44.4, p < .01. You may also report the exact p value (the a posteriori probability that the result that you obtained, or ...

ANOVA procedures culminate in an assessment of the ratio of two variances based on a pertinent F-distribution and this quickly became known as an F-test. As all the procedures leading to the F-test also may be considered as part of the F-test, the terms “ANOVA” and “F-test” have come to be used interchangeably.

We accumulate evidence - collect and analyze sample information - for the purpose of determining which of the two hypotheses is true ...

First, the number of pair-wise comparisons among means can be calculated using the formula: k(k-1)/2, where k = the number of means or levels of the factor being tested. In our present example, the experience factor has four levels so k = 4 and there are k(k-1)/2 = 4(3)/2 = 6 unique pairs of means that can be compared.
