Curve Fitting

Curve Fitting simulation


  • Polynomials
  • Error Analysis
  • Data

Sample Learning Goals

  • Explain how the range and 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
