Answer:
False.
Explanation:
Selecting related samples does not necessarily minimize standard error or increase power. In fact, it can have the opposite effect. Related samples (such as paired samples) are useful when we want to control for certain factors that may affect the measurements, but they may introduce additional variability if the related samples are not truly comparable or if there is measurement error in the related pairs. In general, the best sampling method depends on the research question and the nature of the population being studied.
