Q

Statistical Significance

A

Goal is to get a p value of <0.05. This means that there is a 5% likelihood that the results were due to chance, but a 95% likelihood that the results were due to the intervention.

Good chance that this change would not have been observed if the intervention had no effect whatsoever.

Q

Clinical Significance

A

“Statistical tests alone cannot identify how important the results are to clinical practice.” Clinical significance can be determined by consensus of expert opinion of whether or not it is useful in practice.

Refers to the consistency of a measure. (If you gave the same test over time would the results be reasonably the same? Weighing yourself throughout the day reasonably similar results, not suddenly 50# heavier.)
