Delve into the critical question of when it's truly appropriate to reject the null hypothesis, even when presented with a seemingly significant low p-value. This video explores the nuances beyond just the p-value threshold.
In this insightful discussion, we uncover why simply having a low p-value isn't always enough to confidently reject the null hypothesis, covering key considerations such as:
► Understanding what a p-value actually represents and its limitations in decision-making.
► The critical role of effect size and practical significance alongside statistical significance.
► How experimental design flaws, sample size, and confounding variables can influence p-values.
► The importance of prior knowledge, context, and replication in interpreting statistical results.
► When to exercise caution and consider further research, even with statistically 'significant' findings.
