I am putting together a bid which states: "you should provide information about both your issued and achieved sample sizes, along with appropriate power calculations".

The dataset I am using has the whole population. Could I say:

"I will be studying the whole population, therefore I do not need to state the power"

And how best to word it?

    $\begingroup$ In almost every case where people claim they have the whole population, they do not: this claim is usually based on a misunderstanding of the meanings of "population" and "sample" in a statistical analysis (which are subtle). If you truly have an entire population, then there is no need for statistical estimates, p-values, power calculations, or the like. On the other hand, you have no basis to draw inferences to anything beyond that population, either: you are engaged in a purely descriptive exercise. $\endgroup$

1 Answer 1


I would state it a little differently - people could misinterpret "I do not need".

I will be studying the whole population. Therefore, power calculations are not applicable and not necessary.
