Hypothesis testing checks if sample data provides enough evidence to reject a null hypothesis (status quo). The alternative hypothesis posits an effect or difference. For example, testing if a new drug is more effective than a current standard: H₀: no difference, H₁: drug is more effective. Statistical methods (z-test, t-test) measure if observed data significantly deviates from H₀ assumptions. A p-value < α (significance level) suggests rejecting H₀. Hypothesis testing is foundational in science, business analytics, and policymaking, ensuring data-driven decisions. Mastery fosters rigorous interpretation of test results and minimized false conclusions.
