A researcher analyzed the results of her data and calculated the standard deviation of scores at 3.5. What is the variance?
Question 2 Correct! 2 / 2 pts Suppose we compute the standard deviation and find that it is equal to 5.50. This number means that the numbers in the sample deviate, on the average:<br> Suppose we compute the standard deviation and find that it is equal to 5.50. This number means that the numbers in the sample deviate, on the average:
2.25 units from the mean. 5.50 units from the two extreme scores. Question 3 Correct! 2 / 2 pts Sixteen college freshmen were asked to record the number of alcoholic drinks that they typically consume in a week. Here are their data: 2, 4, 6, 0, 1, 10, 9, 0, 6, 3, 6, 8, 5, 4, 6, 2.
