Look out for results that are reported as “statistically significant” or “not statistically significant”.
In treatment comparisons, statistical significance is the probability of the observed difference (the effect estimate) or a bigger difference having occurred by chance if in reality there was no difference.
However, statistical significance does not tell us anything about how important an effect is. A small, unimportant effect can be “statistically significant”. Similarly, a large, important effect can be “statistically non-significant”.
REMEMBER: Claims that results were significant or non-significant usually mean that they were statistically significant or statistically non-significant. This is not the same as important or not important. Do not be misled by such claims.Warning: count(): Parameter must be an array or an object that implements Countable in /customers/6/e/b/thatsaclaim.org/httpd.www/wp-content/themes/thatsaclaimorg/single.php on line 52
