To assess their basic understanding of statistics, students were asked to identify eight statistical symbols (F, df, t, r, [X.sup.2], p<.05, Xbar or M, and SD or S) that commonly appear in research articles and that have been used in previous investigations of student knowledge of statistics (Witkin et al., 1980).

Meanwhile, math classes learn probability and the Xbar and R charts manufacturers need, incorporating computer software such as Microsoft Excel.
Although the X-chart is less sensitive to changes in parameters of the underlying process, many of the non-random patterns detected by the Xbar and R charts will also be detected by the X-chart -- although "less precisely" according to the Western Electric Handbook[6, p.
