This is because scientists can draw various influential conclusions and statements about data which clearly fits into normal distribution. These statements and conclusions however, may not be done about data that cannot be suitable for normal distribution. Consequently, researchers and statisticians in many cases, transform various distributions into normal distribution, since normal distributions help in providing more statistical information (Gravetter & Forzano, 2012.
