Class size of a distribution having 28, 34, 40, 46 and 52 as its class...
Solve this questions like this:
We observe that 10 - 6 = 4, 14 - 10 = 4 .. so one.
We observe that 10 - 6 = 4, 14 - 10 = 4 .. so one.
Hence, the class size is 4.
Now, the difference between the values of two consecutive class marks is 4, therefore we subtract 4/2 = 2 from each class mark to get the lower limit of the corresponding class interval and add 5 to each class mark to get the upper limit.
Thus, the class intervals are
4 - 8
8 - 12
12 - 16
16 - 20
20 - 24
24 - 28
28 - 32

Class size refers to the width or range of each class interval in a frequency distribution. It is the difference between the upper class limit and the lower class limit of each interval. In this case, we are given the class marks of a distribution, which are the midpoints of each class interval.
To determine the class size, we need to find the difference between consecutive class marks. Let's calculate the differences between the given class marks:
Class marks: 28, 34, 40, 46, 52
Differences: 34 - 28 = 6
40 - 34 = 6
46 - 40 = 6
52 - 46 = 6
As we can see, the differences between consecutive class marks are all equal to 6. Therefore, the class size of this distribution is 6.
Hence, the correct answer is option D) 6.
