A multifactor ANOVA is used to analyze designs only with 3 or more independent variables (factors). False, a multifactor ANOVA is used for designs with 2 or more independent variables. false True true False There is an A x B interaction if the effect of A is different at level 1 of B than it is at level 2 of B. True, by definition, an interaction occurs when the effect of one independent variable differs as a function of the level of another independent variable. true True false False There is an interaction if one variable affects the level of another variable. Variables affect the dependent variable, not the levels of another independent variable. false True true False A sports performance researcher was interested in determining the effect height (short, average, and tall) has on basketball performance during childhood and adolescence. Which is an example of a factor, level? c and e. A factor is an independent variable such as height or age. Each independent variable (such as height) has a number of levels (such as short or tall). It is important to distinguish between an independent variable, which is the variable that is being deliberately manipulated by a researcher and a dependent variable (such as basketball performance) which is dependent upon an independent variable manipulation. false a. short, average false b. basketball performance, average true c. height, short false d. childhood, adolescence true e. age, child
