Mathematics Multiple Choice Questions on “Presentation of Data”.
1. From the table given below, the marks of which the highest frequency exists is __________
| Marks | Students |
|---|---|
| 3 | 1 |
| 4 | 2 |
| 5 | 2 |
| 6 | 4 |
| 7 | 5 |
| 8 | 3 |
| 9 | 2 |
| 10 | 1 |
| Total | 20 |
a) 5
b) 7
c) 10
d) 20
Answer: b
Clarification: The total number of students which have got particular marks is called frequency of those marks.
We can see from the figure that highest number of students is 5 who have got 7 marks.
Therefore, for 7 marks there exists the highest frequency.
2. Consider the runs scored by 11 players in a match which are given below. What is the range of this given data?
8 22 64 16 32 29 16 2 7 15 1
a) 63
b) 64
c) 1
d) 223
Answer: a
Clarification: Range of the data can be given by the following formula:
Range = Highest value – Lowest value
Highest value and lowest value from the data are 64 and 1 respectively.
Hence, range = 64 – 1
= 63.
