Key Concepts

P-value

A p-value is a measure used in statistical hypothesis testing to quantify the evidence against the null hypothesis. It represents the probability of obtaining results as extreme as, or more extreme than, those observed if the null hypothesis were true. Lower p-values indicate stronger evidence against the null hypothesis.

Statistical Significance

Statistical significance refers to the likelihood that a result or effect observed in a study is not due to random chance. When a study's p-value is below a pre-determined threshold (often 0.05), the result is considered statistically significant, suggesting that the effect is unlikely to be due solely to random variation.

Hypothesis Testing

Hypothesis testing is a framework used in statistics to decide whether there is enough evidence to reject a null hypothesis. It involves comparing the p-value to a significance level (alpha) to determine if the observed data provide sufficient evidence to suggest a real effect or difference exists.
