The image displays a table with two columns: "Marks" and "No. of students." Here is the information extracted from the table:

| Marks | No. of Students |
|-------|-----------------|
| 5     | 6               |
| 10    | 8               |
| 15    | 6               |
| 20    | 9               |
| 25    | 20              |
| 30    | 33              |
| 35    | 39              |
| 40    | 45              |
| 45    | 50              |

It appears that this is a frequency distribution table representing the marks obtained by students in an exam.

Would you like help calculating any specific statistics, such as the mean, median, mode, or variance of the data?

Here are 5 relative questions:
1. What is the arithmetic mean of the marks obtained by the students?
2. How would you calculate the median from this frequency distribution?
3. What is the mode of this dataset, based on the number of students for each mark?
4. Could you calculate the standard deviation for these marks?
5. How does the shape of the distribution affect the measures of central tendency?

**Tip**: For grouped frequency data, the midpoint of each class is often used in calculations like the mean.

Given a table showing the marks obtained by students in English and the number of students for each mark, calculate statistical measures such as the mean, median, and mode.

This problem involves analyzing the frequency distribution of marks obtained by students in an English exam. Learn how to calculate statistical measures like the mean, median, and mode using this data. Suitable for high school students, this problem covers key statistical concepts such as measures of central tendency.
