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.

The given data set is C,A,B,B,A.

The following is the process for determining the frequency distribution of qualitative data:

- List the various values in the first column.

- Use tally marks to represent the number of times each value in the data set appears in the second column.

- In the third column, count the amount of tally marks and enter the frequency.

The given data set is C,A,B,B,A.

The relative frequency is calculated as follows:

$\text{Relative Frequency}=\frac{\text{Frequency}}{\text{Number of Observations}}$

The given data set is C,A,B,B,A.

MINITAB has been used to create the pie chart.

The portion for each class in a pie chart is calculated by multiplying $360°$by the appropriate relative frequencies.

The steps of drawing a pie chart are as follows:

- Navigate to Graph > Pie Chart.

- Choose the chart that counts unique data.

- Pick your data.

- Go to the Labels tab.

- Navigate to the Slide Labels tab.

- Under Label pie pieces, check Category name and Percent.

- Click OK

The given data set is C,A,B,B,A.

MINITAB has been used to create the bar chart.

The steps to making a bar chart are as follows:

- Navigate to Graph > Bar Chart.

- Select Counts of unique values from the Bars represent menu.

- Click OK after selecting Simple.

- Enter one column of DATA in Categorical variables.

- Select your chart options

- Click the Show Y as Percent option.

- Click OK
