Rasch Meta-Metres of Growth for Some Intelligence and Attainment Tests

af David Andrich

This book adapts Rasch's approach for quantifying growth on physiological variables, where growth decelerates, to intellectual variables. To apply this approach, it is necessary to construct measurements in a constant unit over the relevant range of the variable. With such measurements, the book illustrates the approach to quantifying growth on six intellectual variables - two intelligences tests and two each of tests of proficiencies in reading comprehension and mathematics. The book discusses ... (Læs mere)
