Repeated-measures ANOVA Suppose you are interested in studying whether scent affects spatial reasoning abilities. You decide to test spatial reasoning using completion time scores u z&quiz;_probGuid-QNAPC0A801 01 0000003ebda430070000&ctxz; Trisha M.Chase-0005&ck;=m 152208991 5615 0AAA051D01 ? ? Aa Aa for the paper-folding test with five people, repeating the test on each person with three different scents (cinnamon, lavender, and peppermint) In this experiment, the null hypothesis is that: O The completion time mean for at least one scent is different from another O There are no differences in the mean completion times among the scents compared There are no individual differences in the completion time means The factor of interest is the scent , and the dependent variable is the completion time . The results of the study are presented in the following data table. All scores are times necessary to complete the paper-folding task, recorded in seconds. Scent Lavender 3.42 3.31 3.93 3.91 4.16 Participant Cinnamon Peppermint Participant Totals 3.22 3.27 3.47 3.46 3.35 3.69 3.74 3.82 P 10.10 P 9.93 P 11.09 P 11.08 P 11.33 N 15 G 53.53 3.35 2X2 192.1709 Session 58:19 12:46 PMExplanation / Answer
Anova Table
The critical value of F at the level of significance 0.05 and degrees of freedom (2,8) is 4.459
The null hypothesis will be rejected we do conclude that scent affects special reasoning abilities.
Hope this is helpful.Thank You
