Construct a grouped frequency distribution table with a width of $10$ for each class,starting from $0-9$.
To construct the grouped frequency distribution table,we identify the class intervals starting from $0-9$ with a width of $10$. The intervals are $0-9, 10-19, 20-29, 30-39, 40-49, 50-59, 60-69, 70-79, 80-89, 90-99$.
By tallying the marks for each interval,we obtain the following frequency distribution table:
By tallying the marks for each interval,we obtain the following frequency distribution table:
| Class Intervals | Frequency |
| $0-9$ | $4$ |
| $10-19$ | $7$ |
| $20-29$ | $5$ |
| $30-39$ | $8$ |
| $40-49$ | $5$ |
| $50-59$ | $8$ |
| $60-69$ | $5$ |
| $70-79$ | $9$ |
| $80-89$ | $6$ |
| $90-99$ | $3$ |
