Question No. 1:



Using the following data: 51, 13, 46, 49, 15, 16, 19, 18, 13, 48, 25, 36, 45, 52, 25, 50, 14, 36, 21, 45, 32, 40, 23, 21, 11, 25, 16, 18, 34, 32.



Solution:

1) Range = Max Value – Min Value

= 52 – 11

= 41



2) 7 Classes Frequency Distribution

First we found Class Width



Class Width = Range / Number of Classes

Number of Classes already given = 7

Now put in formula

= 41 / 7

= 5.85

= Round up 5.85 to 6

= 6



3) Relative Frequency (Column 3)

4) Percentage relative frequency (Column 4)
