Subclaims¶

Reading the evidence codes

q is the design tier, i the impact, n the sample, and the kind with its r the rigour judged within that kind: what each code means.

This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.

q3 i? The data provide evidence of sex differences in the validity of the SAT-M as a predictor of college math performance, but do not allow conclusions about the cause of the score differences. → Howard Wainer 1992

Evidence¶

Howard Wainer 1992¶

Howard Wainer, Linda Steinberg. (1992). Sex Differences in Performance on the Mathematics Section of the Scholastic Aptitude Test: A Bidirectional Validity Study. Harvard Educational Review. https://doi.org/10.17763/haer.62.3.1p1555011301r133

q3 · i? · associational · r2

The authors' interpretive conclusion from the bidirectional validity analysis: matching on college math performance reveals that equal performance corresponds to unequal SAT-M scores by sex, i.e. "sex differences in the validity" of the test as a predictor.

"Though the data do not allow any conclusions about the cause of these differences in SAT-M scores,they do provide evidence of sex differences in the validity of the SAT-M as a predictor of college math performance."

Discussion¶

Learner Variables¶

Gender — moderator: an instructional effect differs by group

Systematic racial, ethnic and gender differences in grades persist among students with the same test scores, attendance, courses and teachers — the general claim this finding bears on, with the studies behind it
Prospective regression analysis of the same data found somewhat larger sex differences in the same direction — related
Women admitted to MIT with lower SAT math scores perform as well as men in freshman math classes — reports the opposite
SAT scores underpredict the academic performance of high school girls, who average lower scores than boys despite higher grades — a broader claim this one bears on
Women scored about 33 SAT-M points lower than men who took the same math course and received the same grade — related
Girls score lower than boys on timed standardized math and science tests at the same course level, and SAT math scores underpredict women's college math performance — related
