Three procedures that help to determine the degree of confidence we can place in any raw score are discussed: computing the standard error of measurement, computing the estimated true score, and constructing confidence intervals. These three procedures are easy to use and require only elementary mathematical skills. (Author/CL)

Mathematical and statistical relationships between factor analysis and smallest space analysis are discussed. As spatial analysis of correlation matrices, factor analysis is a special case of smallest space analysis. The two differ in six ways: Shepard diagram, dimensionality, correction for communality, similarity coefficients, regions versus…

This tutorial summarizes some of the widely known limitations of tests of statistical significance and then focuses on extracting measures of variation accounted for as a supplement to significance testing. Two measures of variation accounted for, eta squared and omega squared, are discussed. Computational formulas, computational examples, and…

Discusses the use of the WORDS computer program in scoring writing assignments. Explains that computerized analysis has identified factors in experienced writers' essays that graders favor but has failed to distinguish clearly between basic and average writers' works. Concludes that holistic scoring can work effectively for student placement, but…

This pamphlet explains a child's Massachusetts Comprehensive Assessment System (MCAS) "Student Report for Parents/Guardians." In spring 1999, more than 210,000 students from grades 4, 8, and 10 in Massachusetts took the state's MCAS tests. All public students in grades 4, 8, and 10 are required to participate, and the Education Reform…

After tests are administered, they are scored and the scores are given back to the students. If the real purpose of the test is to improve student learning, simply returning the scores is not sufficient. The first step in evaluating test results is to be sure that the test has tested the intended concepts and content. Calculating the mean and the…

In eight chapters, this document offers guidelines for school administrators on evaluating schools and school programs, based on a poll of administrators and consultants. The introduction discusses the purpose of evaluation, especially school improvement, and presents a list of evaluation standards. Chapter 1 outlines steps in evaluation planning,…
