Instructional guides for how to run analyses - correct answer c. Any analyses or graphs you have asked SPSS to run When do you use an independent measures t-test? a. When you want to look at whether there are significant differences between two independent groups of participants. b. When you want to compare scores within one group of participants, but from two conditions, all participants take part in both. c. When you want to compare scores within two groups of participants and from two conditions, all participants take part in both. d. When you want to look at whether there are significant relationships between two independent groups of participants. - correct answer a. When you want to look at whether there are significant differences between two independent groups of participants. Which of the following sentences is correct? a. When there is more random variance than experimental variance, an analysis is likely to be significant. b. When there is the same amount of random variance and experimental variance, an analysis is likely to be significant. c. When there is more experimental variance than random variance, an analysis is likely to be significant. d. When there is no experimental variance, an analysis is likely to be significant. - correct answer c. When there is more experimental variance than random variance, an analysis is likely to be significant. When do you use a repeated measures t-test? a. When you want to look at whether there are significant differences between two independent groups of participants. b. When you want to look at whether there are significant differences between two conditions, where you tested the same participants in condition one and in condition two. c. When you want to look at whether there are significant differences between three conditions, where you tested the same participants in all conditions. d. When you want to look at whether there are significant differences between two conditions, where you tested different participants in condition one and in condition two. - correct answer b. When you want to look at whether there are significant differences between two conditions, where you tested the same participants in condition one and in condition two. What is homogeneity of variance? a. It is the assumption that we want to have similar amounts of variance in each of our conditions. When we have homogeneity of variance, then the variability in each of our conditions should be similar. b. It is the assumption that we do not want to have similar amounts of variance in each of our conditions. When we have homogeneity of variance, then the variability in each of our conditions should be different. c. It is the assumption that we want to have different amounts of variance in each of our conditions. When we have homogeneity of variance, then the variability in each of our conditions should be different. d. It is the theory that we want to have similar amounts of observations in each of our conditions. When we have homogeneity of variance, then the number of observations in each of our conditions should be similar. - correct answer a. It is the assumption that we want to have similar amounts of variance in each of our conditions. When we have homogeneity of variance, then the variability in each of our conditions should be similar. When you find that your t test is significant, and you want to interpret your results you should also ______. a. use the non-parametric statistics to help you interpret your findings as without it, you will not be able to interpret which group has significantly higher scores. b. use another statistical test to help you confirm your findings, as without it, you will not be able to interpret your results correctly c. use the descriptive statistics to help you interpret your findings, as without it, you will not be able to interpret which group has significantly higher scores. d. you do not have to do anything, and your results are already significant. - correct answer c. use the descriptive statistics to help you interpret your findings, as without it, you will not be able to interpret which group has significantly higher scores. What are the criteria to determine what value represents a small, medium, and large effect size? Select the correct answer. a. ≥ 2 small effect; ≥ 5 medium effect; ≥ 8 large effect
