an analysis of variance that isolates the main effects of three independent variables, a, b, and c, on a dependent variable and their interaction effects—one three-way interaction, a × b × c, and three two-way interactions, a × b, a × c, and b × c.
the mathematical likelihood of a particular event occurring, as determined by dividing the number of positive outcomes by the total number of possible outcomes. For example, when flipping a coin, the theoretical probability that a tail will occur is 1 divided by 2 (the number of possible outcomes), giving a probability of .5 or 50%.
