In Exercises, we have presented some simple qualitative data sets for practicing the concepts. For each data set,

a.determine a frequency distribution.

b.obtain a relative-frequency distribution.

c.draw a pie chart.

d.construct a bar chart.

A | C | B | A | A | A | B | B | D | D |

Step 1

a)

The frequencies are calculated by using the tally mark. Here the number of times each class repeats is the frequency of that particular class.

Here, “A” is the qualitative data which is repeated for 4 times in the data set and thus 4 is the frequency for the class A.

Similarly, the frequency of remaining classes is given below:

Step 2

b)

*Relative frequency:*

The general formula for the relative frequency is,

Step 3

Similarly, the relative frequencies for the remai...
