In Exercise 4.22 women did not show much difference between Optimists and Pessimists. The first 17 scores in the Optimist group are for men and the first 13 scores in the Pessimist group are for men. What do you find for men?
Answer to relevant QuestionsUse LazStats or MYSTAT to examine the means and standard deviations in Exercise 4.22. (For LazStats use Descriptive/Breakdown. For MYSTAT use the two-sample t test under the hypothesis testing menu and skip over the material ...Given the following data, show that multiplying each score by a constant multiplies all measures of central tendency by that constant. The mean of the data used in Exercise 5.1 is 46.57. Suppose that we had an additional subject who had a score of 46.57. Recalculate the variance for these data. (You can build on the intermediate steps used in Exercise 5.1.) ...Compare the mean, standard deviation, and variance for the data in Exercise 5.1 with their trimmed and Winsorized counterparts. The data in Exercise 5.1 Use the answers to Exercises 5.6 and 5.7 to modify the answer to Exercise 5.8 to have a mean of 0 and a standard deviation of 1.00.
