If the values range from 0 to 60 and there are 6 classes, then the interval is 60/6 = 10.
It s the frequency for the class.
Yes. If the class limit is 0-4.
20-15=5
100
It is the class interval with most number of observations.
The term class interval is used in statistics.
You cannot have a preceding class to the first class. There is no zeroth class.
The class interval for each interval is the difference between its upper limit and its lower limit.
The class interval is 5.
The class interval is the maximum possible value in the class less the maximum possible value in the class below. The second is equivalent to the minimum possible value in the class.
When observations are grouped into class intervals, the interval that contains the most frequently occurring value is known as the modal class.

class interval - one of several convenient intervals into which the values of the variate of a frequency distribution may be grouped.
