Solution

Arranging the given data in ascending order,
5, 9, 10, 12, 15, 16, 19, 20, 20, 20, 20, 23, 24, 25, 25
Mode is the observation that occurred the highest number of times. Therefore, Mode = 20
Median is the middle observation = 20
Yes, the mode and the median are the same for the given observation.
