Hypothesis Testing
Definition
Hypothesis testing is a statistical method used to make inferences or conclusions about a population based on sample data. It involves formulating a null hypothesis and an alternative hypothesis, collecting data, and determining the likelihood of obtaining the observed results if the null hypothesis were true.
Analogy
