Understanding Class Intervals
In a frequency distribution table, class intervals represent the ranges of data grouped together. The size of a class interval is the difference between the upper limit and the lower limit of any class.
Analyzing the Table
From the table, we can observe the following class intervals:
  • 100-125
  • 125-150
  • 150-175
  • 175-200
  • 200-225
  • 225-250
  • 250-275
  • 275-300
  • 300-325
Calculating the Size
Let's take the first class interval as an example: 100-125.
  • Upper limit = 125
  • Lower limit = 100
Size of the class interval = Upper limit - Lower limit = 125 - 100 = 25
Consistent Size
If we calculate the size of other class intervals in the same way, we will find that they all have the same size of 25.
Conclusion
Therefore, the size of the class intervals in the given table is 25.
