This study considers the problem of deciding when a selection test is invalid for members of a minority group. There is both a strong empirical and theoretical basis for rejecting the choice of zero correlation between test and criterion as an appropriate null hypothesis. (Author)

Cross-validation in relation to choosing the best tests and selecting the best items in tests is discussed. Cross-validation demonstrated whether a decision derived from one set of data is truly effective when this decision is applied to another independent, but relevant, sample of people. Cross-validation is particularly important after…

Outlines the purposes of statistical analysis and types of research questions that can be answered. Defines data types as a guide for choosing statistical tools. Describes a hypothetical research study on teaching computer software to illustrate the use of analytical tools. (SK)

Ten item discrimination indices, across a variety of item analysis situations, were compared, based on the validities of tests constructed by using each of the indices to select 40 items from a 100-item pool. Item score data were generated by a computer program and included a simulation of guessing. (Author/CTM)

This study was concerned with determining the validity of the Slosson Intelligence Test (SIT) using the Stanford-Binet Intelligence Scale (S-B), Form L-M as the validity criterion. The sample consisted of 724 students enrolled in 10 public school systems in northeastern Massachusetts. Using the Pearson-Product Moment formula a coefficient of…

The basic concepts, practices, and considerations in assessment are outlined in order to provide the reader with a beginning knowledge of assessment techniques and procedures. Discussion includes the goals of assessment, types of tests, criteria for instrument selection, test construction, data collection procedures, and statistical analysis of…

An analysis was made of quality ratings of elementary level standardized tests. Applying multidimensional scaling to intercorrelations of quality ratings, it was found that the criterion of content and construct validity was a central element in the evaluation of elementary tests. In addition, several types of validity and reliability were found…

The twofold objective of this book is to enable the teacher of English to speakers of other languages both to improve his own classroom measures and to make sound assessments of standardized tests which he may from time to time be asked to select, administer, and interpret. Chapters 1 and 2 introduce the general purposes and methods of language…

The relationship between the Instructional Process, Instructional Objectives, and Assessment Tasks, identified at the School City of Gary, Indiana, necessitate an effective testing program. Four characteristics perceived crucial to a sound program were: (1) The program should be continuous, (2) The testing program should be comprehensive, (3)…

Two types of student response inventories for appraising instruction, the Student Instruction Report (SIR) and the Inventory of Student Perceptions of Instruction (ISPI) were administered to 554 students in 30 classes at two Georgia colleges. Mean responses to items were used in principal components analyses with varimax rotation. The two…

This chapter should not only acquaint the reader with the present state of the art on Criterion-Referenced (CR) measurement but also suggest possible directions for further inquiry. The goal of the first part of this chapter is to deal with the definitional dilemma of CR measurement by proceeding from the more traditional view of CR measurement to…
