Graphs Used to Interpret Data

Explain the difference between a bar graph and a pie chart.

• The bar graph is only used in business, while the pie chart is used in science.

• The bar graph uses squares, while the pie chart uses triangles.

• The bar graph is used for qualitative data, while the pie chart is used for quantitative data.

• The bar graph shows data using bars, while the pie chart shows data using slices of a circle.

In a bar graph, what does the length of each bar represent?

• The font size of the label

• The value of the data

• The color of the bar

• The width of the bar

What type of graph is used to show the parts of a whole?

• Pie chart

• Bar graph

• Scatter plot

• Line graph

How can you interpret data from a pie chart?

• By counting the number of slices

• By analyzing the size of each slice relative to the whole pie, comparing different slices, and identifying patterns or trends.

• By smelling the pie

• By listening to the pie

How can you determine the trend of data from a line graph?

• By observing the overall direction of the line on the graph.

• By counting the number of gridlines on the graph

• By measuring the distance between data points on the graph

• By analyzing the color of the line on the graph

What is the difference between a bar graph and a line graph?

• Pie vs. scatter representation

• Bars vs. lines representation

• Vertical vs. horizontal orientation

• Filled vs. unfilled data points

Why is it important to label the axes in a graph?

• It is unnecessary and time-consuming

• It makes the graph look cluttered

• It provides context and clarity to the data being presented.

• It confuses the audience

What does the color of a line in a line graph represent?

• The font style

• The data value

• The data category

• The background color

What type of graph is best used to represent categorical data?

• Pie chart

• Line graph

• Bar graph

• Scatter plot

How are the data points connected in a line graph?

• By zigzag lines

• By straight lines

• By dotted lines

• By curved lines
