11)The F-test represents the ratio of ________ to the ________. A)mean square due to error; between-groups mean square B)between-groups mean square; within-groups mean square C)between-groups mean square; degrees of freedom D)the degrees of freedom; sum of squares 12)The F-test for a one-way ANOVA can be described in the following way; A)The F is equal to mean square between-groups divided by mean square within-groups. B)The F is equal to mean square between-groups. C)The F is equal to mean square between-groups multiplied by mean square within-groups. D)The F is equal to mean square multiplied by + or – 2.00. 13)If there are no systematic between-groups differences, the F-ratio should have a value of approximately A)9.00. B)-1.00. C)1.00. D)0. 14)The most important method for decreasing the error term is to A)decrease the sample size. B)hold the independent variable constant. C)increase the number of dependent variables. D)increase sample size. 15)The F-ratio can be made larger A)only by increasing the between-groups mean square. B)only by increasing the within-groups mean square. C)by increasing the within-groups mean square or by decreasing the between-groups mean square. D)by increasing the between-groups mean square or by decreasing the within-groups mean square. 16)If the p-value for an F-test is less than the alpha level chosen in the experimental design phase, you should A)reject the null hypothesis and conclude that there is a significant difference between groups. B)reject the null hypothesis and conclude that there is no significant difference between groups. C)accept the null hypothesis and conclude that there is a significant difference between groups. D)accept the null hypothesis and conclude that there is no significant difference between groups. 17)A researcher used SPSS for Windows to perform an ANOVA for an experiment she conducted. In the design phase of the study, she decided to use an alpha level of .05. She should reject the null hypothesis and conclude that there is a significant difference between groups if the p-value is A).10. B)1.0. C).03. D).50. 18)If the mean square between-groups is the same as the mean square within-groups, then A)the F-ratio will be approximately 1.00. B)the experimental manipulations had large effects. C)the differences between experimental conditions are greater than by chance alone. D)the F-ratio will be very large. 19)If there are no systematic differences between the groups, an ANOVA should result in an F-ratio of approximately A)-1.00. B)2.00. C)+1.00. D)0.00 20)An F value of 1.00 or less in an ANOVA indicates A)a significant difference between groups. B)no significant difference within groups. C)no significant difference between groups. D)a significant difference within groups. Â
