Mode of the data 15, 14, 19, 20, 14, 15, 16, 14, 15, 18, 14, 19, 15, 17, 15 is (A) 14 (B) 15 (C) 16 (D) 17

Answer»

B)15

Firstly arrange the ungrouped data in ascending or descending order...

14,14,14,14,15,15,15,15,15,16,17,18,19,19,20

Mode is the most repeated value

From above most repeated value=15

So mode=15....

(B) 15

We first arrange the given data in ascending order as follows 14, 14, 14, 14, 15, 15, 15, 15, 15, 16, 17, 18, 19, 19, 20 From above, we see that 15 occurs most frequently i.e., 5 times.

Hence, the mode of the given data is 15.
