Find the mean and median of the numbers: 4; 6; 4; 7; 2; 3; 8; 9; 7; 4

Solution: 

The values listed in the given problem are :

2, 3, 4, 4, 4, 6, 7, 7, 8, 9

Mean refers to the average of the given data. So if there are four values say p, q, r,  and s then the mean will be (p + q + r + s)/4

The mean of the above set of numbers will be = (2 + 3 + 4 + 4 + 4 + 6 + 7 + 7 + 8 + 9)/10

Mean = 54/10 = 5.40

The median refers to the middle value of the given array of numbers. To find out the median the numbers should be arranged in ascending order. The median will be the middle value.

Since the number of values in the array are even the median value will be the average of the middle two values of the array.

Median = (4 + 6)/2  = 5

Find the mean and median of the numbers: 4; 6; 4; 7; 2; 3; 8; 9; 7; 4

Summary:

The mean and median of the numbers: 4; 6; 4; 7; 2; 3; 8; 9; 7; 4 are 5.4 and 5 respectively.
