Bar Graphs, Circle Graphs, and Dot Plots

Front

What is a bar graph?

Back

A bar graph is a visual representation of data using bars of different heights or lengths to compare quantities across categories.

Front

What is a circle graph (pie chart)?

Back

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

Front

What is a dot plot?

Back

A dot plot is a simple statistical chart that consists of dots plotted on a number line, representing the frequency of data points.

Front

How do you find the mode of a data set?

Back

The mode is the number that appears most frequently in a data set. A data set can have one mode, more than one mode, or no mode at all.

Front

Can a data set have more than one mode?

Back

Yes, a data set can have multiple modes if two or more values appear with the same highest frequency.

Front

What is the median of a data set?

Back

The median is the middle value when the data set is ordered from least to greatest. If there is an even number of values, the median is the average of the two middle numbers.

Front

Can a data set have more than one median?

Back

No, a data set can only have one median.

Front

What does it mean if a bar graph has a higher bar?

Back

A higher bar in a bar graph indicates a greater quantity or frequency for that category compared to others.

Front

How do you interpret a circle graph?

Back

To interpret a circle graph, look at the size of each slice to understand the proportion of each category relative to the whole.

Front

What is the purpose of a dot plot?

Back

A dot plot is used to display the distribution of data points and to identify patterns, clusters, or gaps in the data.
