1. Construct an ungrouped frequency distribution table from the following data
`2,3,7,8,8,5,5,3,7,3,1,8,6,7,4,5,6,3,2,4,3,4,9,8,3`

Solution:
`2,3,7,8,8,5,5,3,7,3,1,8,6,7,4,5,6,3,2,4,3,4,9,8,3`

Here minimum value is 1 and maximum value is 9

x	Tally marks	Frequency
1
2
3
4
5
6
7
8
9
Total

For each value draw a tally mark, next to the x.
`2,3,7,8,8,5,5,3,7,3,1,8,6,7,4,5,6,3,2,4,3,4,9,8,3`

x	Tally marks	Frequency
1	|
2	||
3	||||| |
4	|||
5	|||
6	||
7	|||
8	||||
9	|
Total

Count tally marks to determine the total frequency of each x.

x	Tally marks	Frequency
1	|	1
2	||	2
3	||||| |	6
4	|||	3
5	|||	3
6	||	2
7	|||	3
8	||||	4
9	|	1
Total		`n=25`

The relative frequency

x	Frequency `f`	Relative Frequency `f/n`
1	1	`1/25=0.04=4%`
2	2	`2/25=0.08=8%`
3	6	`6/25=0.24=24%`
4	3	`3/25=0.12=12%`
5	3	`3/25=0.12=12%`
6	2	`2/25=0.08=8%`
7	3	`3/25=0.12=12%`
8	4	`4/25=0.16=16%`
9	1	`1/25=0.04=4%`
Total	`n=25`
