Statistics Pie Chart

What is the first step in data collection for creating a pie chart?

• Create the chart

• Gather data

• Analyze data

• Review data

In statistics, what does a pie chart represent?

• Representation of trends over time

• Comparison of two variables

• Display of geographical data

• Distribution of a whole into parts

What is the total angle in a pie chart?

• 360 degrees

• 90 degrees

• 180 degrees

• 270 degrees

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

• Divide the area of the sector by the total area of the pie chart

• Count the number of categories in the chart

• Calculate the angle of the sector for the category and then use the formula: (Sector angle / 360) * 100%

• Use the color intensity of the category in the chart

What is the purpose of using a legend in a pie chart?

• To confuse the viewer with extra information

• To add unnecessary clutter to the chart

• To provide a key for the different categories represented by the slices of the pie chart.

• To make the chart more visually appealing

Explain the term 'central angle' in the context of a pie chart.

• Central angle is the angle that connects the center of the pie chart to the edge.

• A central angle in a pie chart represents a portion of the total data set.

• Central angle is the angle formed by the intersection of two radii in a pie chart.

• A central angle in a pie chart is the angle at the center of the chart.

What is the difference between a pie chart and a bar graph?

• Pie charts show trends over time, while bar graphs show geographical data.

• Pie charts are used for qualitative data, while bar graphs are used for quantitative data.

• Pie charts are more visually appealing than bar graphs.

• Pie charts show proportions of a whole, while bar graphs compare different categories by their values.

How can you determine the size of each sector in a pie chart?

• Count the number of categories and divide 360 by the count

• Calculate the percentage of each category by dividing the value of the category by the total value and multiplying by 100.

• Use a protractor to measure the angle of each sector

• Guess the size based on personal estimation

What is the most common way to represent data in a pie chart?

• Representing data in a bar chart format

• Using random colors for each section

• Using percentages of the whole circle

• Using Roman numerals instead of percentages

Why is it important to ensure that the data in a pie chart adds up to 100%?

• To accurately represent the distribution of data in a pie chart.

• To show a random distribution

• To make the chart more colorful

• To confuse the audience
