The modeling of longitudinal and multilevel data using a latent variable framework is reviewed. Particular emphasis is placed on growth modeling. Examples are discussed where repeated observations are made on students sampled within classrooms and schools. The concept of a latent variable is a convenient way to represent statistical variation not…

When survey data are statistically analyzed, many times some of the data is missing. If the missing values are not correctly handled, results of the analysis may be dubious and publication may jeopardize the credibility of the organization preparing the report. This study examined four of the more commonly used methods of handling missing data.…

Multivariate methods are being used with increasing frequency in educational research because these methods control "experimentwise" error rate inflation, and because the methods best honor the nature of the reality to which the researcher wishes to generalize. This paper: explains the basic logic of canonical analysis; illustrates that…

A computerized method of preparing a sample of journal issues for testing purposes was created by listing every issue of a set of journals. Random samples of the issues were selected by the computer and printed out. (Author/LS)

The study was designed to establish, on a regional basis, the validity of a set of measures of social handicap as predictive of educational backwardness and to identify the characteristics of those schools which are most compensatory in adverse social conditions. (Editor)

Article considered the preference students have for companies and the criteria each has for accepting employment on the one hand and for employing students on the other hand. (RK)

Sixty-six children aged 9-10 years were tested in two groups with two parallel cloze tests of reading comprehension. The same tests were then given as cloze tests of listening comprehension. (Editor)

Criteria for prediction of multinomial responses are examined in terms of estimation bias. Logarithmic penalty and least squares are quite similar in behavior but quite different from maximum probability. The differences ultimately reflect deficiencies in the behavior of the criterion of maximum probability.

A crucial question in any study is how representative the sample is of the population being studied at the time of the interview. This is of particular concern when the study is based on a follow-up of a sample of respondents initially interviewed for other purposes. This study evaluated the representativeness of a sample of elderly female…

To assess the effect on discriminant analysis in terms of correct classification into two groups, the following parameters were systematically altered using Monte Carlo techniques: sample sizes; proportions of one group to the other; number of independent variables; and covariance matrices. The pairing of the off diagonals (or covariances) with…

A new approach is presented for the meta-analysis of data from pre-test/post-test designs. With this approach, data from studies using different designs may be compared directly and studies without control groups need not be omitted. The approach is based on a "standardized mean-change" measure, computed for each sample within a study,…

This handbook is intended to help educational evaluators use still photography in designing, conducting, and reporting evaluations of educational programs. It describes techniques for using a visual documentary approach to program evaluation that features data collected with a camera. The emphasis is on the aspects of educational evaluation…

The perceptions of teachers in black high schools as compared to teachers in white high schools and the perceptions of black teachers in black high schools as compared to white teachers in black high schools were examined using five variables. (Author/RK)

The position of the "purists" who insist on limiting data to ordinal analysis is contrasted with the "pragmatists" who treat data as interval. (Author)
