Ex 3.2 | Question 3

## Text Solution

Reasoning:

What is known?

The weights (in kg) of $$15$$ students of a class

What is unknown?

The median and mode of this data.

Reasoning:

Mode $$=$$ Mode is the observation that occurs highest number of times

Median $$=$$ Median is the middle observation

Steps:

Total number of students $$=15$$

Weights of $$15$$ students $$= 38, 42, 35, 37, 45, 50, 32, 43,\\ \quad43, 40, 36,38, 43, 38, 47.$$

Arranging in ascending order, we get $$32, 35, 36, 37,38, 38,38, 40, 42, \\43, 43,43, 45, 47, 50$$

(i) Mode is the observation that occurred highest number of times.

Thus$$, 38$$ and $$43$$ occur highest number of times.

$$∴$$ Mode $$= 38$$ and $$43.$$

Also, median $$= 40$$ (8th observation)

(ii) Yes, there are two modes.
