Science Fair-Data Analysis

This Friday, January 18th, the rough drafts of their data analysis, graphs, and data tables are due. The data tables were due last Friday, so those should already be in their folders. Graphs should be drawn on graph paper, I will not accept graphs drawn on regular paper.

The data analysis is a 3 paragraph summary of their data. The first paragraph will discuss patterns in their data, if the independent variable affects the dependent variable (and how), and the averages for their data. It is okay for a student to find that changing the independent variable did not affect the dependent variable! The second paragraph discusses accuracy of the data. They will use the ranges for their data to discuss trends or any lack of a trend. The 3rd paragraph will discuss their limitations. These are usually related to the materials they had available and the number of trials completed.

There is an example of a sample data analysis in the packet of handouts they received, there is also a rubric which they should look over.
