When performing hypothesis testing,

When performing hypothesis testing, many parameter testing methods require the distribution of variables to be normally distributed, otherwise, the corresponding correction formula or other conditions must be used. Sometimes even if the same method uses different formulas, the required conditions are different. Therefore, when choosing statistical analysis methods, you must be clear about the conditions of each method and be able to judge whether the data obtained in the research can use the method. Prevent misuse or use the same method regardless of conditions.
