Viewpoint on Education:

Every student should work at mastering grade-appropriate skills in critical thinking. Critical thinking focuses on identifying and evaluating arguments supporting the truth of disputable claims. Critical thinking focuses on both deductive and inductive arguments. In deductive arguments, the focus is on verifying their validity; in inductive arguments the focus in on evaluating their strength. Inductive arguments focus heavily on explanations, the distinction between reasons and causes, and the distinction between association and causation.

Every student should work at mastering grade-appropriate skills in statistical literacy. Statistical literacy is critical thinking about statistics as evidence for inferences. All college graduates should be statistically literate -- not necessarily about the binomial distribution, probability, sampling distributions and p-values but about those more-informal arguments that use statistics as evidence. Statistical literacy should give students the ability to describe, compare and interpret statistics contained in tables and graphs. Statistical literacy should give students the ability to evaluate the strength of statistics as evidence in arguments about causation. Students should be able to read and critically evaluate statistically-based arguments involving public policy such as The Bell Curve (Herrnstein and Murray), More Guns -- Less Crime (Lott), Population and Development (Simon), The Tyranny of Numbers (Eberstadt), Economics and Politics of Race (Sowell) and Criminal Justice (Bidinotto) as well as the many health related books involving statistics.

 

Statistical Literacy should focus
more on descriptive statistics and modeling
than on statistical inference.
more on reading and interpreting tables and graphs than on sampling distributions.
more on observational studies than on experiments.
more on confounding factors and bias than on chance

more on modeling the association between variables than on the tests of statistical significance
more on inductive inference than on deductive inference.
more on Bayesian reasoning than on classical frequentist reasoning.
more on the quality of statistical arguments about social policy than on the fit of data to theory
more on the support provided by a statistic if true than on the truth of that statistic.
