In a grouped frequency distribution, the class intervals are 0-10, 10-...
Explanation:
A grouped frequency distribution is a tabular representation of data that is divided into intervals or classes, and each class represents a range of values. In this case, the class intervals are 0-10, 10-20, 20-30, and so on.
The class width is the difference between the upper and lower class limits of a class interval. In this case, the lower class limit of the first interval is 0 and the upper class limit is 10. Therefore, the class width is:
Upper class limit - Lower class limit = 10 - 0 = 10
Hence, the correct answer is option A) 10.

In a grouped frequency distribution, the class intervals are 0-10, 10-...
Class width is the difference between the upper limit and lower limit of the class interval.
Therefore,
Class Width = Upper Limit of interval - Lower Limit of interval
In this question the difference between the upper limit and lower limit of each class interval is 10. Hence, the class width is 10. So, option A is correct.
Therefore,
Class Width = Upper Limit of interval - Lower Limit of interval
In this question the difference between the upper limit and lower limit of each class interval is 10. Hence, the class width is 10. So, option A is correct.
