How Do I determine the mean and the median number?

Question

what is the mean and median number of calls received given the following numbers

 52 43 30 38 30 42 12 46 39 37 34 46 32 18 41 5

Answer 1

The mean is the average of all the numbers, and the median is the middle number

The sum of all the numbers is 545.

There are 16 numbers.

So, the average is 34.0625

The numbers in sorted order are:

 

52

46

46

43

42

41

39

38

37

34

32

30

30

18

12

5

 

Since we have an even count (16), the median is half the sum of the 8th and 9th numbers = (37 + 38) / 2 = 37.5

So, the median = 37.5

 

Answer 2

Lexington, to find the mean, you add up all your numbers and then divide by the number of numbers.

 

The mean of 10, 20 and 30 is (10 + 20 + 30) / 3 = 20.

 

The median is the middle number after you put the numbers in order. If there is no middle number, take the two middle numbers, add them together, and divide by 2.

 

The median of 10, 30, 20, 40, 50 is 30.

 

The median of 5, 12, 65 , 35, 25, 3 is (12 + 25) / 2 = 18.5.

 

Hope this helps!
