Testing hypothesis Essay STEP 1: State the hypotheses. STEP 2: Set the criteria for a. STEP 3: Compute the test. STEP 4: Make a decision.
Hypothesis testing is a method of making decisions using data from scientific study. In statistics, a result is called statistically significant if it has been predicted as unlikely to have occurred by chance alone, according to pre-determined threshold probability, the significance level.
Hypothesis testing is defined as the statistical test used by the experienced statisticians to determine the population parameter. It also refers to the procedures used by the analysts to accept or reject the statistical hypothesis. It is used to infer the result of a hypothesis performed on a sample data from a large population.
