Abstract:

Several hundred web-based media stories involving numbers have been analyzed for their statistical content. This content included the description and comparison of counts and measures, percentages and rates, chance and probability. Traditional statistical topics include sample size, confidence level, margin of error, and statistical significance. Non-traditional statistical topics include types of arithmetic association, effect size and the percentage and number of cases attributable to an exposure. Topics involving the statistical context included the type of study (experiment vs. observational, longitudinal vs. cross-sectional, controlled vs. uncontrolled) and the presence of random selection and random assignment. The prevalence of these topics is analyzed and compared. This web-accessible index may help teachers find media stories that illustrate a particular quantitative topic.
