+  abstract =     "Misinterpretation and abuse of statistical tests,
+                  confidence intervals, and statistical power have
+                  been decried for decades, yet remain rampant. A key
+                  problem is that there are no interpretations of
+                  these concepts that are at once simple, intuitive,
+                  correct, and foolproof. Instead, correct use and
+                  interpretation of these statistics requires an
+                  attention to detail which seems to tax the patience
+                  of working scientists. This high cognitive demand
+                  has led to an epidemic of shortcut definitions and
+                  interpretations that are simply wrong, sometimes
+                  disastrously so---and yet these misinterpretations
+                  dominate much of the scientific literature. In light
+                  of this problem, we provide definitions and a
+                  discussion of basic statistics that are more general
+                  and critical than typically found in traditional
+                  introductory expositions. Our goal is to provide a
+                  resource for instructors, researchers, and consumers
+                  of statistics whose knowledge of statistical theory
+                  and technique may be limited but who wish to avoid
+                  and spot misinterpretations. We emphasize how
+                  violation of often unstated analysis protocols (such
+                  as selecting analyses for presentation based on the
+                  P values they produce) can lead to small P values
+                  even if the declared test hypothesis is correct, and
+                  can lead to large P values even if that hypothesis
+                  is incorrect. We then provide an explanatory list of
+                  25 misinterpretations of P values, confidence
+                  intervals, and power. We conclude with guidelines
+                  for improving statistical interpretation and
