Arranging the data in ascending order such that same values are put together, we get:
5, 9, 10, 12, 15, 16, 19, 20, 20, 20, 20, 23, 24, 25, 25
Here, n = 15
Therefore median = ((n+1)/2)th term
Median = value of 8th term
Median = 20
Here, clearly, 20 occurs most number of times, i.e., 4 times. Therefore, the mode of the given data is 20.
Yes, the median and mode of the given data are the same.
