Learn the basics of graphing scientific data, including X-Y coordinates, independent and dependent variables, proper graph formatting, and drawing various types of graphs. Understand how to create accurate graphs for rainfall, temperature, and plant growth data. Improve your data visualization skills for effective analysis and presentation.
E N D
Assign # Sample Graphing 45 pts. • X – Y Coordinates • Shows a change of 2 or more variables • X – Horizontal axis ____________________ Independent variable – variable manipulated or changed by scientist. (Ex. – time)
Sample Graphing • Y – Vertical axis I I • Dependent variable - “Depends” on independent variable The measured variable (ex. - temperature)
Sample Graphing Format • 1) Graphs should cover the whole page • 2) Indent 3-4 lines from sides to bottom • 3) Determine the range of your X and Y axis from table (ex. – x = 0-10, y = 0-80) • 4) Don’t number every square on Y axis. Do every 2, 5, 10, etc.

Each Graph Should Contain: • 1) Title • 2) Labeled X and Y axis • 3) Units for the labeled axis • 4) Line, curve, or bars for coordinates • 5) Labels or legend for each line if multiple line graph
