The author compares new estimates of college dropout rates with earlier studies, examines trends in enrollment rates and degree awards, and presents estimates of enrollment inflows and outflows. (SK)

To guide the unbiased process of visual inference, a four-step model is presented for the assessment of reliability, intervention effect, meaningfulness, and generalizability. A Visual Inference Checklist (VIC) systematizes this assessment process. (Author)

Demonstrates that magnitude-of-effects (ME) estimates vary in susceptibility to sample-size bias depending on whether they are directional or nondirectional estimates. Also demonstrates that study characteristics that influence size of ME estimates can be explicitly taken into account when comparing studies. Emphasizes need to consider study…

Defines structural equation modeling as comprehensive, flexible approach to research design and data analysis. Provides conceptual overview of clinical research hypotheses that invite evaluation as structural equation models. Particular attention is devoted to hypotheses that are not adequately evaluated using traditional statistical models.…

This report summarizes the in-school field operations and data collection activities, as well as the administration decision-making, undertaken in Year 11 of the National Assessment of Educational Progress, (NAEP) from March, 1979 through July, 1980. The more pertinent summary data on the planning and conduct of Year 11 in-school assessment are…

Notes that finding appropriate, statistically sound means of collecting data is important step in developing research. Presents goal attainment scaling and semantic differential as two flexible, reliable, and valid data-collection methodologies useful for practitioners. Provides procedural instructions and examples for constructing each…

Explains multiple regression, demonstrates its flexibility for analyzing data from various designs, and discusses interpretation of results from multiple regression analysis. Presents regression equations for single independent variable and for two or more independent variables, followed by a discussion of coefficients related to these. Compares…
