Tennessee SPI Objective:Interpret and translate data into a table, graph, or diagram.

Notes

Essential Questions

1) What are some effective strategies to help me understand and correctly interpret data from tables, charts, and graphs?

2) What are the differences and specific purposes of a table, circle graph, line graph, and a bar graph?

Check for UnderstandingUse evidence from a dataset to determine cause and effect

relationships in order explain a phenomenon.

Different types of charts, tables, and graphs

Science

Tables

Tables/charts are used to organize and display independent variable and dependent variable information/data.

Tables do not show visual comparisons.

Pie Charts

Best used for comparing parts to a whole. The total amount should equal 100%.

…are circular charts divided into sectors.

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

Line Graph …are used to display data that changes over time

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

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

Bar graphs help us to see relationships quickly.

Bar Graph: ExampleExample: A survey of student's favorite after-school activities was conducted at school. This table shows the results

The data is not changing over time, so a line graph wouldNOT be best for displaying this data. A bar graph is better.
