Describes a study of reliability among coders of information for meta-analysis (a quantitative procedure for synthesizing data in primary research reports) of research on life satisfaction in American adults. Identifies sources and areas of disagreement among coders and discusses measures that can be used to enhance intercoder consistency.…

Outlines the recent transition, within educational research, from conflict to cooperation between quantitative and qualitative approaches. Asserts that compatibility is based on a confusion between method as technique and method as logic of justification. Argues that the claim of compatibility cannot be sustained and blocks an interesting and…

Suggests that because of deficiencies in the statistical analysis and errors of inference, neither the conclusions nor the policy recommencations derived by Coleman are well supported. (Author/AM)

Explores problems involved in the quantitative verification of independent variables in investigations of the effects on student outcomes of planned variations in instructional behavior. Specifically addresses (1) gathering of data through direct systematic observation, and (2) analysis of those data through the use of inferential statistics. (GC)

Scientific rigor, including research design and data analysis, has been established and can now be applied to careful investigations outside the laboratory. This rigor can assist in studying the areas of human development and behavior. Without it, research in natural environments will continue to be inadequate and inaccurate sources of knowledge.…

Examines data analysis at three levels: analysis of data; secondary analysis is the re-analysis of data for the purpose of answering the original research question with better statistical techniques, or answering new questions with old data; and, meta-analysis refers to the statistical analysis of many analysis results from individual studies for…
