Document Summary

Data: 8, 5, 8, 10, 2, 7, 9, 6, 7, 7. First, put in order from lowest to highest: 2, 5, 6, 7, 7, 7, 8, 8, 9, 10: mode: 7, median: 7 + 7= 14/2 = 7, mean: x = 2+5+6+7+7+7+8+8+9+10 ( x=69) (n=10) 69/ 10 = x (with bar on top) = 6. 9. * because all three (mean, median, mode) are very similar it means that the distribution is normal. Data: a set of 50 scores has a x=100. First, we look at the word problem to see what we have . Total of scores = 50 & x = 100: mean: 100/50 = 2. Data: set of 7 scores has a mean of 8. First, we look at the word problem to see what we. Total of scores = 7 & mean = 8 have : mean: 8 = x/7, multiply each side by 7 which gives us 56= x.
