Find the median and mean of the data set below:

Question

7,47,43,47,25,16,18

Answer 1

To find the median, we first arrange the data set in numerical order:

7, 16, 18, 25, 43, 47, 47

Since there are 7 numbers in the set, the median will be the fourth number, which is 25.

To find the mean, we add up all the numbers and divide by the total number of numbers:

(7 + 16 + 18 + 25 + 43 + 47 + 47) / 7 = 203 / 7 = 29

Therefore, the median is 25 and the mean is 29.
