Data Display: Tables and Graphs
Communicating - Conveying oral or written information verbally as well as visually through models, tables, charts, and graphs. Predicting - Proposing possible results or outcomes of future events based on observations and inferences drawn from previous events. Applying process skills to interpret data from graphs, tables, and charts.

Homework Assignment: Poll 25 of your friends to find out their favorite color (blue, green, red, pink, yellow, purple, or orange).

Tables Tables display data in columns and rows to make it easier to read and understand.

Graphs Three types: - Line graph - Bar graph - Circle graph

Line Graph

Line Graph Shows the relationship between two variables.
What is a “variable”? Both variables in a line graph must be numbers. One variable is shown on the horizontal axis, or x-axis, of the graph. The other variable is placed along the vertical axis, or y-axis.

Bar Graph

Bar Graph A bar graph uses rectangular blocks, or bars, of varying sizes to show the relationships among variables. One variable is divided into parts. The second variable must be a number. The bars show the size of the second variable.

Circle Graph A circle graph (“pie graph”) shows the parts of a whole.

Some IMPORTANT Characteristics of Tables and/or Graphs:
A title Labeled columns and rows, or axes Evenly spaced scales Some graphs have keys and/or color-coding. (See the circle graph.)
