Bar Graph or Double Bar Graph (REVIEW)
• A bar graph uses length of bars to represent numbers and COMPARE data.
• In some cases, the use of a pair of bars to compare data is more useful. This kind of graph is called a double bar graph.

How do you make a bar graph?1. Create a title2. Draw an x and y axis (LABEL what each one represents!)3. Plot the information given onto the graph
Example: Last week’s temperatures in degrees Fahrenheit were:Monday- 45 Tuesday- 60 Wednesday- 48 Thursday- 55 Friday- 56 Saturday- 68 Sunday- 70
Let’s make that into a bar graph.

Double Bar Graphs
![Page 6: Bar Graphs. Bar Graph or Double Bar Graph (REVIEW) A bar graph uses length of bars to represent numbers and COMPARE data. In some cases, the use of a.](https://reader036.fdocuments.us/reader036/viewer/2022082421/56649cf35503460f949c1268/html5/thumbnails/6.jpg)
How do you make a double bar graph?
A double bar graph is used to compare two things at once using the same graph. To create a double bar graph you have to…
1. Create a title2. Draw an x and y axis
(LABEL what each one represents!)
3. Make a key to represent what each of the different bars stand for
4. Plot the information given onto the graph
Last week’s temperatures in degrees Fahrenheit were:
Monday- 45 Tuesday- 60 Wednesday- 48 Thursday- 55 Friday- 56 Saturday- 68 Sunday- 70
Last week’s temperature in degrees Celsius were
Monday- 7Tuesday- 16Wednesday- 9Thursday- 12Friday- 13Saturday- 20Sunday- 21

Based on the graph answer these questions:
1. Which day of the week was the hottest in degrees Fahrenheit?2. Which day of the week was the coldest in degrees Celsius?

Histograms

Histogram (REVIEW)• Histograms show how often data falls into
different ranges or intervals.

How do you make a histogram?
Histograms are VERY similar to bar graphs and double bar graphs but:• There are NO gaps between the bars in a histogram.• The x axis is measured in intervals or ranges.
1. Make a title2. Draw an x and y axis (LABEL what
each one represents!)3. Make sure your x axis is in intervals4. Plot the information given onto the
graph

EXAMPLE:You asked customers who bought one of the blue dresses how old they were. The ages were from 5 to 25 years old. You decide to put the results into groups of 5. Then you put the data you collected onto a histogram.
