(a)
Range is the difference between maximum
and minimum values.
=1+4.248019462
-5.248019462
Range-10-2
=8
Using Sturges rule, number of classes can be
determined as follows:
k=1+3.322log N
=1+3.322 log (19)
=1+3.322 x 1.278753601
Class size is given by the formula:
Class size ge
Range
Class Frequency
2-3

4-5
6-7
8-9
10-11
Total
(c)

=1.6
(b) Frequency distribution table for the data is obtained as follows:
Start with the minimum value (2) as the lower limit of the first class. Add 2 to it to
obtain the lower limit of the second class. Keep adding 2 until you get the lower limit of
the 5th class.

5
5
Then, add (2-1=1) to each lower limit to get its corresponding upper limit. Thus, the
frequency distribution table is given below:

The distribution of data is said to be normal based on the symmetrical shape of the
polygon.
