24. Scientific Method Detailed Notes • Collect and Organize Data • Creating Data Tables • Always have a title at the top of the table.

25. Scientific Method Detailed Notes • Collect and Organize Data • Creating Data Tables • Always put units (cm, g, etc.) in column headings.

26. Scientific Method Detailed Notes • Collect and Organize Data • Creating Data Tables • Usually, the Dependent Variable goes in the right columnand the Independent Variablegoes in the left column. **Use 2nd crayon to color “Dependent Variable” and D.V. column. **Use 3rd crayon to color “Independent Variable” and I.V. column. Title:______________________

27. Scientific Method Detailed Notes • Analyze Data (Creating Graphs) • Turn to your Glossary to letter “A”. • Add the words “analyze data” and the page number of your “Scientific Method Detailed Notes” (probably page 22)

28. Scientific Method Detailed Notes • Analyze Data (Creating Graphs) • There are three typesof graphs: • Line graph – continuous data (usually data over time)

40. Scientific Method Detailed Notes • Analyze Data (Creating Graphs) • Interpolation vs. Extrapolation • Interpolation – making a prediction based inside the data • For example, on the following graph there is no specific data for 12 minutes, but we can estimate what it would be because we have data between 10 and 15 minutes.
