Editing Misuse of statistics (section)

===Confusing statistical significance with practical significance===
Statistical significance is a measure of probability; practical significance is a measure of effect.{{sfn|Moore|McCabe|2003|pp=463}} A baldness cure is statistically significant if a sparse peach-fuzz usually covers the previously naked scalp.  The cure is practically significant when a hat is no longer required in cold weather and the barber asks how much to take off the top.  The bald want a cure that is both statistically and practically significant; It will probably work and if it does, it will have a big hairy effect.  Scientific publication often requires only statistical significance.  This has led to complaints (for the last 50 years) that statistical significance testing is a misuse of statistics.<ref name="Rozeboom1960">{{cite journal|last1=Rozeboom|first1=William W.|title=The fallacy of the null-hypothesis significance test|journal=Psychological Bulletin|volume=57|issue=5|year=1960|pages=416–428|doi=10.1037/h0042040|pmid=13744252}}</ref>
