11. 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
Return to Graph

12. 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.
Return to Graph

13. 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
Return to Graph

14. Double Line Graph
 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
- Equal Intervals
- Data displayed by
points connected into
lines
- Key
Return to Graph

15. 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)
Return to Graph

16. 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
Return to Graph

17. 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
Return to Graph

18. Histogram
 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.
Return to Graph

19. Scatter Plot
 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
