P value hypothesis test
WebP Values. The P value, or calculated probability, is the probability of finding the observed, or more extreme, results when the null hypothesis (H0) of a study question is true – the … WebTherefore, the null hypothesis is accepted. Example 2: P-value is 0.3105. If the level of significance is 5%, find if we can reject the null hypothesis. Solution: Looking at the P-value table, the p-value of 0.3105 is greater than the level of significance of 0.05 (5%), we fail to reject the null hypothesis. Example 3: P-value is 0.0219.

WebP Values. The P value, or calculated probability, is the probability of finding the observed, or more extreme, results when the null hypothesis (H0) of a study question is true – the definition of ‘extreme’ depends on how the hypothesis is being tested.

WebP values can be "hacked" to give a significant result when one doesn't actually exist, leading to unreproducible research. Other times researchers approach hypothesis testing backwards, by letting the P value decide the hypothesis after the fact. Confidence intervals give a range of possibilities that are more informative than a P value.
