What type of data is best represented by a pie chart?

• Numerical data

• Time series data

• Categorical data

• Qualitative data

How can you compare the data in different categories using a bar graph?

• By representing each category on the y-axis and the corresponding data values on the x-axis

• By representing each category on the x-axis and the corresponding data values on the y-axis

• By using a scatter plot instead of a bar graph

• By using a line graph instead of a bar graph

How can you calculate the percentage of each category in a pie chart?

• Multiply the size of each category by the total size of the pie chart

• Add the size of each category and then divide by the total size of the pie chart

• Subtract the size of each category from the total size of the pie chart

• Divide the size of each category by the total size of the pie chart and then multiply by 100
