Line the numbers up in order, since they're in reverse order, this is easy:

51 55 61 62 68 71 71 73 81 82 87 89 92 94 95 100

Count the numbers and find the exact middle:
There are 16 numbers, therefore the center will be between 8th and 9th numbers, which are 73 and 81.

In order to find the median, average the two middle numbers (add them together and divide by 2).

The median is the "middle" number when the data are arranged in order (as they already are). Since there are an even amount of numbers (16 of them), the median is the average of the two middle numbers.

In this case, the middle numbers are 73 and 81. Find the average, which is 154 / 2 = 77.

77
When you have an odd quantity of numbers, the median is the one in the middle of the list when you list them in ascending or descending order. When you have an even quantity of numbers, there is no middle number. In this case you take the average of the 2 numbers closest to the middle. In this case, 73 and 81

(81 + 73)/2 = 77

The median has half the data above it and half the data below it. This is the midpoint of an odd number of items, or the average of the two innermost items of an even number of items.
