Sandeep Garg Solutions Class 11 – Chapter 4
Question 1
Prepare a line frequency graph from the following data.
| Marks | 20 | 30 | 40 | 50 | 60 | 70 | 80 |
| Frequencies | 7 | 9 | 11 | 12 | 14 | 15 | 17 |
Answer:
The given data can be presented in a line frequency graph as follows:
Question 2
Represent a histogram from the following data.
| Marks | 0−10 | 10−20 | 20−30 | 30−40 | 40−50 |
| No. of Students | 15 | 30 | 58 | 45 | 35 |
Answer:
The given data can be represented with the help of a histogram as follows:
Question 3
Make a histogram from the following frequency.
| Class Intervals | 2.5 | 7.5 | 12.5 | 17.5 | 22.5 |
| Frequencies | 5 | 10 | 30 | 15 | 6 |
Answer:
Here, the gap between the two mid-values is 5. So, it’s half difference (2.5) will be subtracted and added from each mid-point to get the below-mentioned class intervals.
| Mid-points | Class intervals | Frequencies |
| 2.57.512.517.522.5 | 0 − 55 − 1010 − 1515 − 2020 − 25 | 51030156 |
Question 4
Prepare a polygon with the help of the following frequencies.
| Mid-Values | 5 | 15 | 25 | 35 | 45 | 55 | 65 | 75 |
| Frequency | 4 | 10 | 16 | 22 | 25 | 12 | 7 | 2 |
Answer:
Question 5
Arrange a frequency curve of the following details:
| Class-interval | 10−20 | 20−30 | 30−40 | 40−50 | 50−60 | 60−70 | 70−80 |
| Frequencies | 3 | 7 | 11 | 15 | 13 | 6 | 2 |
Answer:
| Class intervals | Frequencies |
| 10−20 20−30 30−40 40−50 50−60 60−70 70−80 | 3 7 11 15 13 6 2 |
