Option C. Excel. Find an internet site that teaches you how to use Microsoft's Excel program to insert your raw scores and calculate the mean and standard deviation of your data set. Then test the tutorial information by inserting the following population of 8 raw scores: 7, 4, 3, 2, 4, 6, 3, 1. For these data, the mean = 3.75, the population variance = 3.438, and the population standard deviation is 1.854. Incidentally, the range = 7, the modes = 3 and 4, and the median = 3.5. Now what I'd like you to put on the group participation board is the URL (website address) and a review of this tutorial program in terms of user friendliness and how easy it is to absorb the instructions and do it yourself to come up with with the right answers. Rate it in terms of one to five stars, with five stars being "great." Comment about the ease of using this site, and its accuracy (of course). Also comment on any glitches other students might run into. That is, make it easier for other students who may go to this site. Afterward, reply to a classmate.
