Hypothesis Testing
What is Hypothesis Testing?
Hypothesis testing is a statistical method used to make inferences about a population based on a sample. It is a way to determine whether the results of an experiment or study are statistically significant and therefore, whether the results support or reject a specific hypothesis about the population. A hypothesis is a statement or assumption about a property of a population. The goal of hypothesis testing is to determine whether the evidence supports accepting or rejecting the null hypothesis, which states that there is no significant difference or relationship in the population. The process of hypothesis testing includes setting up a null and alternative hypothesis, choosing a test statistic, determining a critical region, and making a decision and drawing a conclusion based on the results.
