Hypothesis testing is a six-step procedure: 1. This helps the child understand the sums better and helps them progress rapidly. To test a statistical hypothesis, you take a sample, collect data, form a statistic, standardize it to form a test statistic so it can be interpreted on a standard scale , and decide whether the test statistic refutes the claim. The variance and standard deviation are closely related to each other; the standard deviation always equals the square root of the variance.
