Frequency Distribution and Class Intervals
Frequency distribution is a way of organizing data into groups or classes based on their values or ranges. It is often presented in a table or chart that shows the number of times each value or range appears in the data set.
Class intervals are the ranges or groups of values used in frequency distribution. They are determined by the size of the data set and the desired level of detail in the analysis.
Solution
To determine the number of class intervals for the given data set, we need to follow these steps:
Step 1: Find the range of the data set
Range = Maximum value - Minimum value
Range = 73 - 44
Range = 29
Step 2: Determine the class length
Class length = (Range / Number of desired class intervals)
Class length = (29 / x), where x is the number of class intervals
Since we want the class length to be 5, we can solve for x as follows:
5 = (29 / x)
x = 29 / 5
x = 5.8
Since we cannot have a fractional number of class intervals, we need to round up to the nearest whole number, which is 6.
Therefore, the number of class intervals, or the number of groups or ranges of values in the frequency distribution table, is 6.
Conclusion
The correct answer is option C, which states that the number of class intervals is 7. However, this answer is incorrect as it is based on the assumption that the first class interval starts at 40, which is not stated in the question. Using the given assumption of a class length of 5, the correct answer is 6 class intervals.

For data on frequency distribution of weights:70, 73, 49, 57, 44, 56, ...
Answer is c, as range = max-min values and the range=29
And when you see frequency distribution highest number is 73 Nd lowest number is 44 so class intervals cannot be from 44-49, then itl become
40-45
45-50
50-55
55-60
60-65
65-70
70-75 no of intervals = 7
