A social psychologist is interested in knowing whether people are more aggressive if they are in the presence of a weapon, such as a gun Treatment Condition- T1, as compared to when they are in a room with an innocuous item such as a tennis racket Control Condition-T2. The study used one sample of 17 college students and had all of the students in the sample participate in both treatment conditions. The mean of the difference scores was 18.0 and the variance (s2) was 612. An alpha level of .01 was set. Calculate the t. A  3.000 B  2.780 C  2.152 D  1.765

Define ADL or GLS: Bias versus variance?

True or False: In order to perform an analysis of variance (ANOVA), the response variable must be quantitative.

Explain the effect of heterogeneity of variance on the Type I error rate?

What correctly represents the coefficient of determination in terms of the variance that is an output from the analysis of variance table?

Please use ANOVA

describe the difference between a one-sample t-test, a two-sample (independent-samples) t-test, a repeated measures (related-samples) t-test, and the analysis of variance (ANOVA).

A researcher wants to measure average cardiovascular health of university students and compare those scores to the average scores in the general population. Assuming that population variance is known, what statistical test is most appropriate for this study?        independent-samples t-test     single-sample t-test     z-test for sample mean     related-samples t-test
