Mean = Sum/Count = 20/5 = 4
The average mean is 4 and 1/7
5 + 3 + 7 + 3 + 2 = 20/5 = 4 The mean of the numbers is 4.

1, 2, 2, 3, 4, 4, 5, 7, 8 Mean: 4 Median: 4 Mode: 2 and 4
It is: 8+7+7+5+3+2+2 = 34/7 => 4 and 6/7 which is the average mean
Standard deviation is the square root of the mean. The mean for this set is (2 + 4 + 3 + 7)/4 = 16/4 = 4; the square root of this is 2.
If you mean 11 and 7/8 divided by 4 and 3/4 then the answer is 2 and 1/2
[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7[(-4) + (-3)]*[(-2 - (-1)] = (-4 -3)*(-2 + 1) = -7*-1 = +7
You add all the numbers together and divide the answer by the amount of numbers. eg 4 7 3 2 4+7+3+2=16 16/4 =2 the mean [ arithmetic ] is 2
Mean: 3 I think the range is 7 or 8
