Chapter 2, Problem 68CR

Is status related to a student’s understanding of science? The article “From Here to Equity: The Influence of Status on Student Access to and Understanding of Science” (Culture and Comparative Studies [1999]: 577-602) described a study on the effect of group discussions on learning biology concepts. An analysis of the relationship between status and “rate of talk” (the number of on-task speech acts per minute) during group work included gender as a blocking variable.

Do you think that gender is a useful blocking variable? Explain.

Dr. Chory found that, regardless of the respondents' personal experience with physicians, those who watched certain kinds of television had declining perceptions of physicians' composure and regard…
