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.

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 (X and Y), which are labeled.

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 evenlyspaced apart from each other.

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.

Line 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.
