Determining power before conducting a study is typically done to determine the number of participants needed to have a reasonable level of power. In other words, it is important to have enough participants in a study to ensure that the study has the ability to detect a significant effect if one exists. This helps to ensure that the study is not underpowered, which could result in a failure to detect a significant effect even if one exists.
