Description

Dengan menggunakan mouse, tariklah data points dan error-bar-nya,sambil memperhatikan bentuk kurva polinomial yang paling mendekati.
Anda dapat memilih bentuk pengepasannya : linier, kuadratik, kubikal atau kuartik. Nilai reduced chi-square statistic akan membe- ritahukan tingkat ketepatannya.
Selain itu anda juga dapat menco- ba mencari bentuk yang paling mendekati secara manual dengan mengatur parameter-parameternya.

Contoh Tujuan Pengajaran

  • 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

Standards Alignment

Common Core - Math

HSS-ID.B.6
Represent data on two quantitative variables on a scatter plot, and describe how the variables are related.
HSS-ID.B.6a
Fit a function to the data; use functions fitted to data to solve problems in the context of the data. Use given functions or choose a function suggested by the context. Emphasize linear, quadratic, and exponential models.
HSS-ID.B.6b
Informally assess the fit of a function by plotting and analyzing residuals.
