Question

If the calss marks of a distribution are 23,27,31,35,39.Find class size and class limits

Answer 1

Answer:

5, 21---25

Step-by-step explanation:

Given If the class marks of a distribution are 23,27,31,35,39. to find class size and class limits.

Now we can find class size = 27 - 23 = 4

We know  that a is the class interval and h is the class size.

Lower limit of a class interval is given by a - h/2 = 23 - 4/2 = 23 - 2 = 21

Upper limit of a class interval is given by a + h/2 = 23 + 4/2 = 23 + 2 = 25

So upper limit is 25 and lower limit is 21

So we get the class limit as 21-----25. We can write the rest of the limits as

25-----29, 29------33, 33------37, 37------41 and so on.
