“…One author (Myers, 1969) reports differences with probabilities less than .O1 as &dquo;particularly evident,&dquo; &dquo;important,&dquo; and &dquo;sizable&dquo; whereas another difference, significant at the .05 level, is only &dquo;a mild tendency.&dquo; Comparative differences in the level of statistical significance do not necessarily indicate the presence of a strong relationship between independent variables and dependent variables. Many authors, although they do not attempt to interpret strength of relationship from differing probability values in the text, report differing values of p in their recording of the statistical results (i.e., p < .02, for one value of the F statistic, p < .005 for another, and so on).…”

Whereas statistical significance indicates whether a difference is a difference, additional information signifying whether the difference is large enough to make the results worth acting upon is included in practical significance. Statistical measures of practical significance report the extent to which variation in the dependent variable can be explained by the independent variable. Measures of practical significance are seldom reported in The Journal of Special Education, although sometimes issues of practicality are discussed using the estimate of statistical significance. Practical significance, however, may vary greatly among samples even though statistical significance estimates are similar.
