1. A human-factors psychologist studied three computer keyboard designs. Three samples of individuals were given material to type on a particular keyboard, and the number of errors committed by each participant was recorded. Are these data sufficient to conclude that there are significant differences in typing performance among the three keyboard designs? Calculate and interpret effect size if appropriate. Be sure you include a sentence demonstrating how a research report would present the results, Keyboard A Keyboard B Keyboard C VICO N = 15 G - 60 2 6 XX2 - 356 T - 5 T = 25 T = 30 SS = 12 SS = 20 SS = 14
