Interpreting Circle Graphs

Front

What is a circle graph?

Back

A circle graph, also known as a pie chart, is a circular statistical graphic divided into slices to illustrate numerical proportions.

Front

What does each slice of a circle graph represent?

Back

Each slice of a circle graph represents a category's proportion to the whole, often expressed as a percentage.

Front

How do you calculate the percentage for a slice in a circle graph?

Back

To calculate the percentage for a slice, divide the part (value of the slice) by the whole (total value) and multiply by 100.

Front

If 100 students were surveyed and 35 chose vanilla, what percentage chose vanilla?

Back

35% chose vanilla.

Front

If 200 students were surveyed, how many would choose vanilla if the percentage remains the same?

Back

70 students would choose vanilla.

Front

True or False: The total percentage in a circle graph must equal 100%.

Back

True.

Front

What is the maximum number of slices a circle graph can have?

Back

There is no strict maximum, but it should be limited to ensure clarity; typically, 5-10 slices are ideal.

Front

True or False: Percentages in a circle graph can be greater than 100%.

Back

False.

Front

What does it mean if a category in a circle graph has a larger slice?

Back

It means that category has a larger proportion of the total compared to others.

Front

If a circle graph shows 25% for transportation, what fraction does that represent?

Back

1/4 of the total.
