Unformatted text preview: 2. For the data gathered in class: Do this exercise twice, once with your group and once with one of the other groups. a. Compute the grand mean of the time values by dominant and non-dominant hand. b. Compute the total amount of variation. c. Compute the variation, variance, and standard deviation of the times for the dominant hand and then again for the non dominant hand. d. What is the unaccountable variation and how much variation is accountable by knowing which hand was used? e. Calculate eta squared f. What other independent variables might account for some of the variability? Explain. Your group Second group Grand mean SST SSacct SSunacct Eta square Variances for dominant hand and for non-dominant hand Standard Deviations for dominant and non-dominant Variations for dominant and non-dominant...
