Question: Calculate LSD for the two experiments in Exercise 1 of the previous chapter. For which experiment is the calculation of LSD justified? Determine which pairs

Calculate LSD for the two experiments in Exercise 1 of the previous chapter. For which experiment is the calculation of LSD justified? Determine which pairs of means differ significantly in the experiment for which the calculation of LSD is justified.

Data from exercise 1(previous chapter)

Following are two separate (hypothetical) sets of data that are somewhat exaggerated to help clarify the procedures underlying analysis of variance. In each case, the experimenter is interested in conditions that affect the number of errors made by participants on a simple clerical task that must be performed quickly. Group 1 listens to upbeat dance music while performing the tasks; Group 2 listens to soothing, New Age music; and Group 3 listens to white noise (e.g., the steady hum of a machine in the background).
