Graphing

Communicating With Graphs • What is a graph? – Visual display of information or data – Used to recognize patterns in data – Different kinds of graphs express different types of information

Bar Graph • Compares information collected by counting. • Used to compare things between different groups.

Line Graph • A line graph shows a relationship where the dependent variable changes due to a change in the independent variable. • Both variables will be numbers.

Circle graph/pie chart • Shows the relationship of parts to a whole. (%)

• Independent – On a graph, the independent variable is placed on the x axis.

• Dependent Variable – On a graph, the dependent variable is placed on the y axis.

Rules for Graphing 1. Identify: – x-axis and independent variable (The horizontal line on a graph) – Y-axis and dependent variable (The vertical line on a graph) 2. Choose the SCALE - don’t be afraid of the graph paper, fill it up! 3. Pick proper increments – choose values that are easily divided! – All graphs do not have to begin at zero (0) – how big are the numbers you are using 4. Label each axis – feet, seconds, etc. . 5. Title the graph! The y-axis vs. x-axis 6. Create a Key! – if you are comparing data, then tell the reader, what each line or color stands for
