Question

What is the median of this data set?

56, 82, 93, 86, 89, 53, 74, 72, 55, 97

Answer 1

Sort the numbers in increasing order. Then pick out the middle-most data value to find the median.

Answer 2

Since there are an even number of values, this means that you'll have 2 middle-most values.

The median will be the average of those two values

Answer 3

Remember to put them in increasing order first! And then follow @jim_thompson5910 advice and find the mean of the 2 medians.
just in case you forget:
mean = the sum of the numbers, divided by 2(there are two integers)

Answer 4

Using R:

> z<-c(56, 82, 93, 86, 89, 53, 74, 72, 55, 97)
> median(z)
[1] 78
> sort(z)
[1] 53 55 56 72 74 82 86 89 93 97
