# The weights (in kg.) of 15 students of a class are:

38, 42, 35, 37, 45, 50, 32, 43, 43, 40, 36, 38, 43, 38, 47

(i) Find the mode and median of this data

(ii) Is there more than one mode?

**Solution:**

We use the basic formulae of mode and median to solve the question.

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

Median = Median is the middle observation

Total number of students =15

Weights of 15 students = 38, 42, 35, 37, 45, 50, 32, 43,43, 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.

The weights (in kg.) of 15 students of a class are: 38, 42, 35, 37, 45, 50, 32, 43, 43, 40, 36, 38, 43, 38, 47 (i) Find the mode and median of this data. (ii) Is there more than one mode?

i) 38 and 43 occur highest number of times and are thus the mode of the given observation. Median is equal to 40, ii) ). Yes, there are two modes.
