Question

Explain the meaning of the following terms: True Class Limits

Answer 1

True Class limits: When we group a number of variates together then the lowest value of the variate and the highest value of the variate form the class limits.
Let the class intervals for some grouped data be 10 - 20, 20 - 30, 30 - 40 etc. This is an exclusive frequency distribution. For the class 20 - 30, 20 is the lower limit, while 30 is the upper limit. Here the limits are actual and are called true class limits.
