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.
