0. 2 sd or more, the diff is of little value or importance, even if its stat sig. Ci--confidence level is the complement of the level of sig, i. e. a 95% ci reflects sig level of 0. 05. The ci contains the parameter values that, when tested, should not be rejected w. the same sample. If ci is narrower w. lower variability & higher sample size it becomes more precise, likely values cover smaller range. If i increase coverage by using 99% calculation it becomes more accurate, true value more likely to be w/n range. The larger the margin of error, the less confidence one should have. P value informs reader whether effect exists, p value wont reveal size of effect interpreting studies, substantive sig (ef) &stat sig (p value) are essential results.
