Question
Construct a grouped frequency distribution table with width $10$ of each class, in such a way that one of the classes is $10-20 (20$ not included).
✓
Answer
We arrange the given data into groups like $0-10, 10-20, 20-30$ in which upper class limit is not included in that class. The class width in each case is $10$. The frequency distribution of the given data is given below:
