# The scores in mathematics test (out of 25) of 15 students is as follows:

19, 25, 23, 20, 9, 20, 15, 10, 5, 16, 25, 20, 24, 12, 20

Find the mode and median of this data. Are they same?

**Solution:**

We use the basic formula and definitions of mode and median to solve the problem.

Scores of 15 students in mathematics test are:

19, 25, 23, 20, 9, 20, 15, 10, 5 16, 25, 20, 24, 12, 20.

Arranging scores in ascending order, we get

5, 9, 10, 12, 15, 16, 19, 20, 20, 20, 20 , 23, 24, 25, 25

Mode - Mode of a given data is that value of observation that occurs for the most fnumber of times, that is, most frequently.

Therefore, 20 occurs most of the time.

∴Mode = 20.

Median = middle of observation (in this case, 8th observation)

∴Median = 20

Yes, mode and median of the given observations are same.
