Question

List situations in which it is useful to consider​ power, indicating what the use is for each.

Select all (multiple) that apply.

Question 31 options:

	A. During the​ experiment, to decide whether changing the power could result in a more desirable outcome.
	B. After a study is done that had nonsignificant​results, to evaluate whether the result should be attributed to the null hypothesis being true​ (in the​high-power situation) or to inadequate power so that it is still reasonable to think that future research might have a chance of being significant.
	C. When planning an​ experiment, to permit changes of various kinds​ (or even abandon the​ project) if power is too low​ (or possibly to make the study less​ costly, for example by reducing the number of​ participants, if power is higher than reasonably​needed).
	D. After a study is done that had significant results with a large sample. In this​ case, if power is very​high, this suggests that a low effect size is​possible, so that although the result is​ significant, it may not be very important.

Answer 1

ANSWER:

List situations in which it is useful to consider​ power, indicating what the use is for each:

We have to obtained the in which it is useful to consider​ power, indicating what the use is for each is ,

Here,

The correct statement for the given situations is

• When planning an​ experiment, to permit changes of various kinds​ (or even abandon the​ project) if power is too low​ (or possibly to make the study less​ costly, for example by reducing the number of​ participants, if power is higher than reasonably​needed).

Therefore ,

OPTION (C) is correct answer for the given statement .
