EXERCISE 3.2
E
1. The scores in mathematics test (out of 25) of 15 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?
2. The runs scored in a cricket match by 11 players is as follows:
6, 15, 120, 50, 100, 80, 10, 15, 8, 10, 15
Find the mean, mode and median of this data. Are the three same?
3. 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
(1) Find the mode and median of this data.
(i) Is there more than one mode?
4. Find the mode and median of the data: 13, 16, 12, 14, 19, 12, 14, 13,
5. Tell whether the statement is true or false:
(1) The mode is always one of the numbers in a data.
(ii) The mean is one of the numbers in a data.
(iii) The median is always one of the numbers in a data.
(iv) The data 6, 4, 3, 8, 9, 12, 13,9 has mean 9.​

Answer 1

Step-by-step explanation:

Qno.1 mode= maximum frequency

=20

median= 15+1/2

=16/2

= 8th

so ans = 8th position of the num in assending order series so,ans is 19

mode and median are not same.
