Q.4 Find the mode and median of the data:
13, 16, 12, 14, 19, 12, 14, 13, 14

Arranging the given data in ascending order we get:

12,12,13,13,14,14,14,16,19

Here, 14 occur 3 times (highest)

Thus, mode = 14

n = 9(odd)

Therefore Median = (n+1)/2 th term =(9+1)/2 th term
= 5th term = 14
Hence, mode = 14 and median = 14.
