Detailed explanation-1: -Normal data is test data that is typical (expected) and should be accepted by the system. It is important to include normal data as part of a testing plan.
Detailed explanation-2: -If your data is approximately normal, then you can use parametric statistical tests.
Detailed explanation-3: -"Normal” data are data that are drawn (come from) a population that has a normal distribution. This distribution is inarguably the most important and the most frequently used distribution in both the theory and application of statistics.
Detailed explanation-4: -The test relies on a set of assumptions for it to be interpreted properly and with validity. Among these assumptions, the data must be randomly sampled from the population of interest and the data variables must follow a normal distribution.
