## What data Cannot be shown on a double bar graph?

## What is a triple bar graph?

A double bar graph may be used to compare the survey answers of one group verses another group. A triple bar graph may be used to compare data recorded over a three day period or over several days. … Create a multiple bar graph to display and compare the amounts of vegetables sold over the three day period.

## What is a double line graph used for?

Double Line Graph A graph that compares two different subjects over a period of time. A double line graph shows how things change over a period of time. The double line graph shows two line graphs within one chart. Double line graphs are used to compare trends and patterns between two subjects.

## How do you describe a bar graph in statistics?

A bar graph breaks categorical data down by group, and represents these amounts by using bars of different lengths. It uses either the number of individuals in each group (also called the frequency) or the percentage in each group (called the relative frequency).

## What is the difference between a bar graph and a double bar graph?

A bar graph is a graphical display of data using single bars of various heights. A double bar graph is a graphical display of information using two bars besides each other at various heights. … We can use a double bar graph to compare two data groups. A double bar graph has two axes.

## Why would you use a bar graph over a line graph?

Bar graphs display data in a way that is similar to line graphs. Line graphs are useful for displaying smaller changes in a trend over time. Bar graphs are better for comparing larger changes or differences in data among groups.

## How is a histogram different from a bar graph?

Histograms are used to show distributions of variables while bar charts are used to compare variables. Histograms plot quantitative data with ranges of the data grouped into bins or intervals while bar charts plot categorical data. … Note that it does not make sense to rearrange the bars of a histogram.
