Re: Sainani K. Interpreting “null” results

Professor Sainani starts her article [1] by stating that the notion that a lack of statistical significance (P> .05) constitutes proof of no effect is a common misconception in statistics. She thereafter uses logical reasoning and illustrative examples to explain to the reader why this is a misconception, and finally winds up with some very useful recommendations on how to interpret statistical test results when P> .05.
