Bar Graph

The purpose of a bar

graph is to display and

compare data.

Bar graphs use bars toshow 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 fromeach other

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.

Pictograph

All pictographs have a

title.

Rows and columns

shape the pictograph.

Label each row and

column.

http://www.khanacad

Use pictures to show

the data.

Each picture equals a

certain amount of

data.

Pictographs need a

key.

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



Double Line Graph

A double line graph is

used to compare two

groups of related dataover time.

Double line graphs

need:

- Title

- Labeled X and Y axes

- Equal Intervals

- Data displayed bypoints connected into

lines

- Key

Return to Graph



Circle Graph

Circle graphs are

used to display parts

of the data in relationto 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



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, butthe compared bars

are not

- Key

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



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



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

Return to Graph



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 asordered pairs
