Important Questions on Class 7 Maths Chapter 3

The scores in mathematics test (out of 25) of students is as follows: 19, 25, 23, 20, 9, 20, 15, 10, 5, 16, 25, 20, 24, 12, 20. Find the mode and median of this data. Are they same?

Arranging the given data in ascending order:
= 5, 9, 10, 12, 15, 16, 19, 20, 20, 20, 20, 23, 24, 25, 25
Mode is the observation occurred the highest number of times.
Therefore, Mode = 20 Median is the middle observation = 20
Yes, Mode and Median are same of given observation.

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

Arranging the given data in ascending order, 12, 12, 13, 13, 14, 14, 14, 16, 19
Mode is the observation occurred the highest number of times = 14
Median is the middle observation = 14

Tell whether the statement is true or false: The mode is always one of the numbers in a data.

True.
