For instance, Wifi enabled means the device can use Wifi, and that it's Wifi antenna is turned on. If you disable Wifi, it's the same as turning it off. PoohBearPenguin Â· 2 years ago
This situation is unusual; if you are in any doubt then use a two sided P value. The term significance level (alpha) is used to refer to a pre-chosen probability and the term P value is used to indicate a probability that you calculate after a given study.
$P = 0.0023$ does not mean $\alpha = 0.0023$ unless one has decided to use $0.0023$ as the critical level for significance when the experiment is designed. If you would have taken $P = 0.05$ as significant then $P = 0.0023$ means that there is an $0.05$ probability of a false positive claim.P = 0.0023$ does not mean $\alpha = 0.0023$ unless one has decided to use $0.0023$ as the critical level for significance when the experiment is designed.
