Find the median and mean of the data set below:

Question

40,38,1,19,8,36,40

Answer 1

To find the median, we first need to arrange the data set in numerical order:
1, 8, 19, 36, 38, 40, 40

Since there are an odd number of values (7), the median is the middle number which is 19.

To find the mean, we add up all the numbers in the data set and then divide by the total number of values:
(1 + 8 + 19 + 36 + 38 + 40 + 40) / 7 = 182 / 7 ≈ 26

Therefore, the median is 19 and the mean is approximately 26.
