"What If" Analyses: Ways to Interpret Statistical Significance Test Results Using EXCEL or "R"
Ozturk, Elif
Online Submission, Paper presented at the Annual Meeting of the Southwest Educational Research Association (35th, New Orleans, LA, Feb 1-4, 2012)
The present paper aims to review two motivations to conduct "what if" analyses using Excel and "R" to understand the statistical significance tests through the sample size context. "What if" analyses can be used to teach students what statistical significance tests really do and in applied research either prospectively to estimate what sample size might be needed in a study, or retrospectively in interpreting research results.
