1. A researcher is interested in whether participants will differ in their attitudes toward drinking while driving if they watch a video on the dangers of drinking. He has seven participants watch a video on the dangers of drinking while driving and then asks them to rate their attitudes toward drinking and driving. He then asks five different participants, who do not watch the video, to rate their attitudes toward drinking and driving. Attitudes toward drinking and driving Experimental Group (watched video) M = 10.57 SD - 1.62 n =7 Control Group (did not watch the video) M=13.80 SD = 2.28 n = 5 A. Identify the levels of the IV B. Identify the DV C. Compute the appropriate test of differences using the formula and table of critical values attached. Show all your work. D. Interpret and Report your results in sentence format including the descriptive statistics (means, standard deviations, and mean difference if appropriate), inferential statistic (), df, a measure of statistical significance (p) and practical significance (d). For full credit, use the format provided in the t- test handout. /
