Answer:

Given Observations: 16, 18, 20, 19, 20, 5, 20

Most common term, ie, Mode = 20 because it occurs the maximum number of times.

Mean = (16+18+20+19+20+5+20)(7) = 118/7 = 16.85 approx.

To find the median, we need to arrange the data in either ascending or descending order. Here, I'll arrange the data in ascending order.

5, 16, 18, 19. 20, 20, 20

No. of observations (n) = 7

This means that n is odd. Then, median = (n+1)/2 th term = 7+1/2 th = 8/2 th = 4 th term.

Here, the 4th term is 19.

Hence, the median is 19.
