Urgent need for help!
An article given the mean and standard deviation of Sleep latency and Sleep duration of PSQI, how can I convert the mean and standard deviation of the scores of these two parts?
Hi,
Scoring/interpretation: Scoring is on a 0 – 3 scale, with 3 being the negative extreme. A total sum of 5 or more indicates a “poor” sleeper.
