It is impossible to ever prove that H ₀ is true because _________. A) the power to detect very weak but real effects of the independent variable is always low B) chance is a vague concept C) very strong real effects of the independent variable swamp out chance D) power decreases as N decreases

Question

Quizplus · Accepted Answer

The power to detect very weak but real effects of the independent variable is always low, meaning it's difficult to prove something is true if the effect size is very small. This is because statistical power, which is the probability of correctly rejecting the null hypothesis when it is false, is influenced by the effect size, sample size, significance level, and variability. Small effect sizes require larger sample sizes to achieve the same level of power, making it challenging to prove hypotheses about very weak effects.
