14. Bar Graph The purpose of a bar graph is to display and compare data.
Return to Graph
Bar Graph
The purpose of a bar graph is to display and compare data.
Bar graphs use bars to show the data.
A bar graph must include:
- a title
- labeled X and Y axes
- equal intervals are used on the Y axis
- the bars are evenly spaced apart from each other

15. Return to Graph
Stem and Leaf Plot
Stem and leaf plots are used as a quick way of seeing how many pieces of data fall in various ranges. The reader can quickly tell:
- the range
- the mode
Stem and leaf plots have a title, a stem, and leaves
A key is used to explain how to read the stem and leaves.

16. Pictograph All pictographs have a title.
Return to Graph
Pictograph
All pictographs have a title.
Rows and columns shape the pictograph.
Label each row and column.
Use pictures to show the data.
Each picture equals a certain amount of data.
Pictographs need a key.

17. Line Graph A line graph is used to illustrate change over time.
Return to Graph
Line Graph
A line graph is used to illustrate change over time.
Line graphs need:
- Title
- Labeled X and Y axes
- Equal Intervals
- Data displayed by points connected into lines

18. Return to Graph
Double Line Graph
- Equal Intervals
- Data displayed by points connected into lines
- Key
A double line graph is used to compare two groups of related data over time.
Double line graphs need:
- Title
- Labeled X and Y axes

19. Return to Graph
Circle Graph
Circle graphs are used to display parts of the data in relation to the entire amount of data.
All circle graphs need a title.
Each part is called a sector and is labeled.
All angles correct (+2/-2 degrees)

20. Return to Graph
Double Bar Graph
The purpose of a double bar graph is to compare two or more sets of data.
Uses bars to show the data.
Double bar graphs must include:
- Title
- Labeled X and Y axes
- Equal intervals are used on the Y axis
- Pairs of bars are equally spaced, but the compared bars are not
- Key

21. Return to Graph
Line Plot
A line plot shows the spread of all the data on a number line.
Easily identifies the mode.
All line plots include:
- a title
- a numbered horizontal line
- data displayed by use of X’s

22. Histogram Histograms are used to show the frequency of data.
Return to Graph
Histograms are used to show the frequency of data.
Very similar to bar graphs, but use intervals on the X axis.
Bars do touch.
Histograms have a title.
Histograms have two axes which are labeled.

23. Box - and - Whisker Plot Displays large set of data.
Return to Graph
Box - and - Whisker Plot
Displays large set of data.
Gives general idea of how data clusters.
Graph includes:
- Title
- Labeled intervals
- Box between lower and upper quartiles
- Whiskers from quartiles to extremes
- Median, quartiles and whiskers labeled

24. Scatter Plot Shows how closely two sets of data are related
Return to Graph
Shows how closely two sets of data are related
The closer the sets are related, the closer the points come to forming a straight line.
Scatter Plots include:
- title
- labeled axes
- equal intervals
- corresponding numbers plotted as ordered pairs
