How to solve median with two numbers
WebOct 18, 2016 · 1 Answer Sorted by: 1 We know the mean is 7 and that there are six numbers, so the sum of all numbers is 42. It follows that the sum of the two unknowns is (1) x + y = 42 − ( 4 + 5 + 7 + 10) = 16 Now use the formula for variance (which is the square of the standard deviation): σ 2 = 13 3 = 1 N ∑ i ( x i − μ) 2 WebThe first step is to calculate the mean (average) of the set of data. If we have the set of data [-1,2,3,7,9,12,17], the mean would be [-1+2+3+7+9+12+17] / 7, so 7 is the mean. The second step is to measure how far each point of data is from the mean, so [7- (-1)] + [7-2] + [7-3] + [7-7] + [7-9] + [7-12] + [7-17].
