Simple data fitting explorer

Live Script illustrating interactive and programmatic fits of data to a polynomial model.

This Live Script illustrates the interactive polynomial fitting tool functionality available in a figure window and how to perform such fits programmatically in order the access parameter errors. It is designed to process data from a first lab in introductory physics course with computation. 'Try this' suggestions and 'Challenges' are included for further exploration. For a more advanced introduction to curve fitting, see Ref[1].
