The process hinges on calculating a p-value, which represents the probability of obtaining the observed results, or more extreme results, if the null hypothesis were actually true. It typically asserts that there is no relationship between two measured phenomena, or that a potential treatment has no effect.
Practical Steps for Rejecting the Null Hypothesis Correctly
This declaration centers on the status of a formal assumption known as the null hypothesis, a foundational concept in inferential statistics. Additionally, failing to reject the null hypothesis is not evidence that the null is true; it may simply indicate that the study was underpowered to detect the existing effect.
If the p-value is less than or equal to alpha, the result is deemed statistically significant, and the null hypothesis is rejected. A researcher establishes a significance level, most commonly alpha (α) at 0.
Practical Steps for Rejecting the Null Hypothesis
This hypothesis is not assumed to be true in an absolute philosophical sense, but rather operationalized as a baseline to challenge with statistical evidence. Furthermore, statistical significance does not equate to practical importance; a result can be highly significant statistically yet trivial in real-world impact.
