|Title||Curve Fitting: How well does the curve describe the data? (Inquiry Based)|
|Description||This activity could be used in any course where students are asked to understand how well a curve describes a set of data. These are a few of the Learning Goals: Students will be able to: Explain how the range, uncertainty and number of data points affect correlation coefficient and Chi squared; Describe how correlation coefficient and chi squared can be used to indicate how well a curve describes the data relationship; Apply understanding of Curve Fitting to designing experiments|
|Subject||Chemistry, Mathematics, Physics|
