B****l 发帖数: 22 | 1 I want to conduct a power analysis for correlated observations. My question is whether it is OK to treat the correlated observations at two time points (the same group of people) as independent, and conduct the corresponding power analysis for independent t-test. The reason is I want the sample size to be small, say, around 10.
Somebody told me if the sample size is large, we can treat correlated observations as independent. Otherwise, we cannot. I am not sure. Thanks. |
