Researchers collected the following set of data: 4, 8, 9, 9, 14, 14, 14, 24. If the mean of the data equals 12, which value equals the sum of squares?
Added by Francisco Javier E.
Step 1
To find the deviation of each data point from the mean, we subtract the mean from each data point. Deviation of 4 = 4 - 12 = -8 Deviation of 8 = 8 - 12 = -4 Deviation of 9 = 9 - 12 = -3 Deviation of 9 = 9 - 12 = -3 Deviation of 14 = 14 - 12 = 2 Deviation of 14 = Show more…
