Question

construct a frequency distribution table from the given data. 5,3,6,4,5,2,4,2,3,6,5,4,2,1,4,7,3,2,1,6.
​

Answer 1

Step-by-step explanation:

First the arrange the data in order

1,2,2,2,2,3,3,4,4,5,5,6,6,7,7,8

The largest number =8

The smallest number =1

Range = largest number - smallest number =8−1=7

Hence, we shall calculate an approximate group size, by dividing the range by the number of groups we want.

If we want 3 groups, then Divide range with number of groups =

3

7

=2.333

The class interval width will be 3. Start from 0.

Class interval Frequency

0−3 5

3−6 6

6−9 5
