Question

Question 6
The class marks of a continuous distribution are 1.04, 1.14, 1.24, 1.34, 1.44, 1.54 and 1.64.
Is it correct to say that last interval will be 1.55 - 1.73? Justify your answer.

Answer 1

It is not correct. Because the difference between two consecutive class marks should be equal to the class size.
Here, the difference between two consecutive marks is 0.1 and class size of 1.55 - 1.73 is 0.18, which are not equal.
