Whitney, Douglas R. – American Educational Research Journal, 1972
This paper describes two statistics (chi square and Kendall's S) which may be used to test hypotheses about the association between two variables when observations are cross-classified in a contingency table. (CK)

Jerman, Max – Journal for Research in Mathematics Education, 1970
Examined were the mental processes by which elementary school students work simple multiplication exercises. Ten process models were fit to data obtained in the course of a CAI program in elementary arithmetic. The processes used by students in grade three were compared with those used by students in grade six. (CT)

Fischbach, Thomas J.; Walberg, Herbert J. – Journal of Educational Psychology, 1971
The methods used by Humphreys and Dachler to estimate effects in their analysis of Project TALENT data to test Jensen's Theory of Intelligence are shown to produce biased estimates. (Author/TA)

Brumfiel, Charles – Arithmetic Teacher, 1971
Before judging a student's diagram correct or incorrect, the mental associations made by the student between his diagram and the problem should be known. This is a follow-up to the author's article in the November 1970, Arithmetic Teacher." (RS)

Innis, George – BioScience, 1971
Describes a program in which students develop a mathematical model, based on simple feedback loops, used for predicting consequences of varying ecological parameters. Presentation early in undergraduate course emphasizes use of statistics in ecology. (AL)

Hopkins, Kenneth D. – American Educational Research Journal, 1982
The recommendation to use group means when there may be nonindependence among observational units is unduly restrictive. When random factors are properly identified and included in the analysis, the results are identical in balanced analysis of variance designs, irrespective of whether group means or individual observations are employed.…

LaBerge, David – Journal of Experimental Psychology: Human Perception and Performance, 1983
In two experiments, a probe technique required subjects to respond when the digit 7 appeared in one of five-letter positions in words or nonwords, inserted at the onset and 500 msec after letter and word processing. The focus of attention given to a letter has a smaller spatial extent. (Author/CM)
