WAPP: Web-based Analysis Program for Physics
How Much Uncertainty ("y error")?
WAPP aims to determine the parameters of a function (e.g., a and b for
the linear function y=a+bx) which
"best" represents your x-y data pairs. "Best" is defined in terms
of how much the calculated y values deviate from the y values
you determined experimentally compared to the expected error caused
by less-than-perfect measuring instruments ("y error").
(Technically WAPP is based on ordinary least squares with deviation assumed
in the y coordinate.) There are several ways you can report
this expected "error" in your y-values:
