It is:- (86+89)/2 = 87.5
It is 89, the value halfway between the two middle values.
86
86
The idea is to sort the numbers, and pick the number in the middle as the median. In cases like this, when you have two numbers in the middle (the size of the set is even), take the average of those two numbers.
For 98 78 86 88 84 81 93 92 89 and 81: σ=6.2361
Well, darling, the median is the middle number when the numbers are listed in order. So, in this case, when you line up those numbers in numerical order, the middle number is 86. Voilà, that's your median.
Put them in order, least to greatest. 62, 78, 84, 89, 94, 94, 96, 98 The range is the smallest subtracted from the largest. 98 - 62 = 36 The range is 36. The median is the average of the middle two. 89 + 94 = 183 divided by 2 = 91.5 The median is 91.5
To find the median of a set of numbers, you first need to arrange them in numerical order. Once you have them in order, the median is the middle number. If there is an odd number of values, the median is the middle number. If there is an even number of values, the median is the average of the two middle numbers. In this case, the numbers arranged in numerical order are: 78, 81, 82, 88, 88, 88, 89, 91, 91, 92, 93, 94, 95, 96, 98. Since there are 15 numbers, the median will be the 8th number, which is 89.
They are: 62 63 64 65 66 68 69 70 72 74 75 76 77 78 80 81 82 84 85 86 87 88.

78 x 89 = 6942
the median is 785
