SPI 0807.Inq.3: (Interpret Data)Notes

Different types of charts, tables, and graphs

Science

Tables

Tables/charts are used to organize exact amounts of data and to display numerical information.

Tables do not show visual comparisons.

Pie Charts

Best used for comparing parts to a wholeThe total amount should equal 100%

A pie chart is a circular chart divided into sectors

Works well for comparing 6 or fewer items, but more than six items becomes difficult to view and interpret

Bar Graph Bar graphs are used to compare facts. The bars provide a visual display for comparing quantities in different categories  

Bar graphs help us to see relationships quickly.

Example: A survey of student's favorite after-school activities was conducted at school The table shows the results

Note: Since the data is not changing over time, a line graph would not be best for displaying this data. A bar graph is better.

Line Graph Line graphs are used to display data or information that changes continuously over time.

Line graphs allow us to see overall trends such as an increase or decrease in data over time.
