05, which acts as an evidentiary threshold. This hypothesis is not assumed to be true in an absolute philosophical sense, but rather operationalized as a baseline to challenge with statistical evidence.
Understanding Statistical Significance in Hypothesis Testing
Implications for Scientific Inquiry The decision to reject the null hypothesis functions as a critical gatekeeper in the scientific method, filtering out explanations that lack empirical support. Rejecting the null hypothesis is the decisive action a researcher takes when the evidence presented by the data proves sufficiently inconsistent with the assumption of no effect or no difference.
Conversely, a test with high power is more sensitive to detecting small, meaningful effects. A rejection of the null hypothesis does not prove that the alternative hypothesis is correct, nor does it quantify the magnitude of an effect.
Understanding Statistical Significance in Hypothesis Testing
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.
