Question

1. An analysis of variance with one dependent and one independent variable is referred to as: A) one-way ANOVA B) two-way ANOVA C) many-way ANOVA D) correlation 3.        What is the null hypothesis when using ANOVA? A) 1 = 1 B) $\mu1 = \mu2=\mu3...=\mu n$ C)   D)    4.         What is the research hypothesis when using ANOVA procedures? A)        all of the group means are equal B)        all of the group means are significantly different from all other group means C)        at least one of the group means is significantly different from the others D)        none of the above 7. When using ANOVA, one is interested at the outset in calculating what is known as the within group sum of squares. What does this quantity measure? A) the sum of the squared deviations between each group mean and every other group mean B) the sum of the squared deviations between each group mean and the mean across all groups C) the sum of the squared deviations between each individual observation and its group mean D) the sum of the squared deviations between each individual observation and the mean across all groups 10. Which of the following is NOT part of the process of using ANOVA procedures? A) specifying the null and research hypotheses and selecting an alpha level B) selecting the sampling distribution and specifying the test statistic C) computing the test statistic and interpreting the results D) all of the above are part of the process of using ANOVA

Answer 1

(a) Cooperation as cooperation in takes into consideration the relationship between dependent and independent variables (b) mu_1 = mu_2 = mu_3 = ....... mu_2....... mu as ANOVA is to test equality of more than two population averages (c) at least one of group menus is significantly different from the others mu_i notequalto mu_j fan at least one set of (i , j) (c) the sum of the squad deviation between each individual observation and its group mean (d) all of the above are part of the process of using ANOVA
