Question
Your study is only valid if your p-value is < 0.05.
Group of answer choices
- True
- False
Solution
The statement, "Your study is only valid if your p-value is < 0.05," can be viewed with some nuance in the context of statistical hypothesis testing and scientific research.
-
Understanding P-values: P-values measure the strength of the evidence against the null hypothesis. A p-value less than 0.05 is commonly used as a threshold to indicate statistical significance, suggesting that the observed data would be unlikely under the null hypothesis.
-
Context Matters: While a p-value < 0.05 is often considered a standard criterion for significance, it does not alone determine the validity of a study. Other factors like study design, sample size, and reproducibility are critical for drawing reliable conclusions.
-
Misinterpretation Risks: The strict reliance on p-values can lead to misinterpretations, such as considering a p-value just above 0.05 as not significant. Moreover, a study may yield meaningful results with a p-value higher than this threshold, especially in exploratory research.
In summary, while a p-value < 0.05 is a useful guideline for statistical significance, the validity of a study is not solely dependent on this threshold. Therefore, the correct answer is False. Scientific validity encompasses a broader range of factors beyond just the p-value.
