Car Crash Tests? If we use the data described in Exercise with two-way analysis of variance, we get the accompanying display. What do you conclude? Exercise Two-Way ANOVA? Data Set 13 in Appendix B lists results from car crash tests. Included in results from car crash tests are loads (pounds) on the left femur and right femur, and those values are shown in the table below. What characteristic of the data suggests that the appropriate method of analysis is ?two-way? analysis of variance? That is, what is “two-way” about the data entered in the table?
Solution 5BSC Step 1: From the given information the data is based on the car crash tests are loads on left femur and right femur. From the given Minitab display is given as follows: Step 2: F rom the above output . For interaction factor: The test statistic is F = 1.72 and the p-value is 0.194. Comparing the p-value with significance level 0.05. Here the p-value is larger than the significance level. So there is no sufficient evidence to conclude that that there is an interaction effect.
