BASIE is a framework for interpreting impact estimates from evaluations. It is an alternative to null hypothesis significance testing. This guide walks researchers through the key steps of applying BASIE, including selecting prior evidence, reporting impact estimates, interpreting impact estimates, and conducting sensitivity analyses. The guide…

Written by a social worker for social work students, this is a nuts and bolts guide to statistics that presents complex calculations and concepts in clear, easy-to-understand language.

Provides a practical introduction to methods of constructing confidence intervals for multiple and partial "R" squared and related parameters in multiple regression models based on noncentral distributions. Illustrates software use (e.g. the Statistical Package for Social Studies) for confidence intervals and discusses measures of effect…

A procedure and a computing diagram for assigning score boundaries to grading categories on classroom tests are described. The procedure takes both the median ability level of the class and the test performance of the class relative to that of other classes into account. (Author)

The reports that teachers receive from the Portland (Oregon) Public Schools Achievement Level Testing Program are planned to help them to see how each individual student is doing, which students need help, and how the class is performing as a whole.

This paper presents a new technique in which covariates are controlled and evaluation data still are presented graphically in a manner that makes sense to policy makers. An illustration is provided using data drawn from an evaluation by the author of a major National Science Foundation (NSF) university funding program. (Author)

A statistical model is presented for processing quantitative admission data that weights equally two or more quantitative elements to ensure that the N most consistently high scorers qualify for the N available positions. The quantitative elements considered are overall grade point average (GPA), GPA in selected courses, and standardized test…

Reviews problems involved in analyzing data on educational or training needs and details use of the proportionate reduction in error (PRE) approach (Hildebrand, et al., 1977), which predicts the probability that certain combinations of a joint distribution will occur, then tests to see how closely the prediction matches the observation. (MBR)

This manual is a first effort to begin to identify, describe, and develop procedures for assessing various aspects of digital reference service. Its overall purpose is to improve the quality of digital reference services and assist librarians to design and implement better digital reference services. More specifically, its aim is to: assist…

Designed to assist school jurisdictions in interpreting their achievement test results, this report describes the achievement testing program in Alberta, Canada, and indicates the conditions for student exemption from testing.
