What Confidence Intervals "Really" Do and Why They Are So Important for Middle Grades Educational Research
Skidmore, Susan Troncoso
Middle Grades Research Journal, v4 n2 p35-55 Sum 2009
Recommendations made by major educational and psychological organizations (American Educational Research Association, 2006; American Psychological Association, 2001) call for researchers to regularly report confidence intervals. The purpose of the present paper is to provide support for the use of confidence intervals. To contextualize this discussion, a brief account of what null hypothesis statistical significance testing (NHSST) does and does not do as well as a sensible alternative to NHSST precedes the discussion of confidence intervals. Next, accessible instructions for computing confidence intervals and related graphics are provided to encourage and facilitate usage. Finally, recommendations are discussed that will facilitate the collective research enterprise. (Contains 5 figures and 1 table.)
