Question 1 2 ptsMonika wants to measure the amount of money that different graduate school students spend on fast food (measured in dollars). She selects 20 random graduate students at CSUN, 20 random graduate students at UCLA, and 20 random graduate students from USC. She then measures the total amount of money each student spends on fast food at the end of one week. She wants to see (overall) if the amount of money spent by students is significantly different across the different schools. Which type of analysis is appropriate to test for this?Group of answer choicesFactorial ANOVAOne-way ANOVATukey HSD testScheffe adjustmentQuestion 2 2 ptsJohn conducts a one-way ANOVA to compare 4 different groups (using an a = 0.05) and finds that they are significantly different from each other. He is interested in seeing which groups are significantly different from each other, so he conducts a Tukey HSD post-hoc test afterwards (using a = 0.05). However, he wants to make sure that his total Type I error for the one-way ANOVA and the post-hoc test is only 5% (not 10%). Using a Bonferroni adjustment, what would his new alpha level be?Group of answer choices0.010.01250.0250.017Question 3 2 ptsYou design a study to be a 2 x 3 Factorial ANOVA. Choose the correct amount of independent variables and levels in each independent variableGroup of answer choices2 independent variables, 6 levels in the 1st independent variable, 6 levels in the 2nd independent variable3 independent variables, 2 levels in the 1st independent variable, 2 levels in the 2nd independent variable2 independent variables, 2 levels in the 1st independent variable, 3 levels in the 2nd independent variable3 independent variables, 3 levels in the 1st independent variable, 3 levels in the 2nd independent variableQuestion 4 2 ptsIn a one-way ANOVA, the Within Groups Error we calculate is based on the difference of each individual's DV score from their group's mean. Group of answer choicesTrueFalseQuestion 5 2 ptsWhen you only have two different categorical groups in your IV, performing a dependent samples t-test and a one-way ANOVA will result in the exact same p-value.Group of answer choicesTrueFalseQuestion 6 4 ptsYou run four different one-way ANOVAs. You would like to reduce your Type I error (because after these 4 tests, your Type I error chance is ~20%)! Based on the number of tests you ran, you determine that you need to lower your alpha level to 0.0125 for each ANOVA. If each ANOVA has 3 groups in it (a = 3) and each group has 16 participants (s = 16), what is your new critical F value with this lower alpha level?(Round your answer to two decimal places)Question 7 4 ptsAfter conducting a one-way ANOVA, you find that there are significant differences across four different groups. Each group has an equal number of people in it, so you decide to follow this one-way ANOVA with a Scheffe adjustment to see which of these groups are significantly different from each other. You calculate the final Scheffe value to be 3.256. Based on the means of each group (below), identify ALL of the following groups that are significantly different from each other...Group 1: 5.248 Group 2: 7.589 Group 3: 8.562 Group 4: 3.123Group of answer choicesGroup 2 vs. Group 4 Group 3 vs. Group 4Group 1 vs. Group 3 Group 2 vs. Group 4 Group 3 vs. Group 4Group 1 vs. Group 2 Group 2 vs. Group 3 Group 1 vs. Group 4Group 1 vs. Group 3Group 2 vs. Group 3Question 8 2 ptsTo do a 2x2 factorial ANOVA by hand, you need to have way too much time on your hands, a lot of formulas written down, and a lot of practice (especially for exam 3). (Choose answer "Yes" below -- it is the correct answer)Group of answer choicesNoMaybeYesI don't know!Question 9 6 ptsGiven the data for a one-way ANOVA (below), calculate the Sums of Squares Between Groups.

Group of answer choicesTrueFalseQuestion 13 2 ptsWhich of the following is an example of a simple effect analysis in a Factorial ANOVA?Group of answer choicesThere are significant differences across all groups of the 1st IV.There are significant differences across all levels of the 1st IV, but only for one level of the 2nd IV,There are significant differences across all combinations of groups from both IV1 and IV2.In the 1st IV, group 1 is significantly different than group 2, but group 1 is not significantly different than group 3.Question 14 4 ptsCalculate a Tukey HSD value for a one-way ANOVA (based on the following information)...qT = 4.201 MS (within) = 21.88 n = 15Group of answer choices6.1286.86576.115.5355.07Question 15 2 ptsGiven the following group means from a 2 x 2 Factorial ANOVA: Variable A Group 1 Group 2 Variable B Group 1 20 40Group 2 20 40Which variables (if any) show a main effect?Group of answer choicesThere is a main effect of both Variable A and Variable B.There is no main effect for either Variable A or Variable B.There is a main effect of Variable B only.There is a main effect of Variable A only.Question 16 2 ptsIf you have designed a research study with 1 categorical IV (which is split into three separate groups) and 1 ratio DV, you should use a one-way ANOVA to determine if there are any significant differences across all of the groups. Group of answer choicesTrueFalseQuestion 17 2 ptsIn a one-way ANOVA, the three main factors that influence Within Group error are:1. How close the group means are to each other2. How spread out the variances of the groups are3.
