Tests of Hypotheses Using Statistics
... The method of hypothesis testing uses tests of significance to determine the likelihood that a statement (often related to the mean or variance of a given distribution) is true, and at what likelihood we would, as statisticians, accept the statement as true. While understanding the mathematical conc ...

We know an “A” is higher than a “C”, but we don’t know by exactly by how much. “Strongly Disagree” is an opinion which is very different from “Strongly Agree,” but exactly how different is unknown.
