Abstract
A QBASIC program for curve fitting for othogonal polynomials within ex perimental design is presented. It studies trend analysis, its signifi cance and the proportion of explained variace and also the value of th e coefficients for a priori orthogonal tests of differences between me ans. It is valid for the general case of unequally spaced and weighted treatment levels design.
