The normal distribution is one of the most fundamental concepts in statistics and probability theory. Also known as the Gaussian distribution or the bell curve, it is used to mathematically model many phenomena observed in nature, society, and engineering sciences. In particular, in fields such as biology, economics, psychology, engineering, and quality control, the normal distribution serves as the primary reference point for understanding the behavior of data sets. Definition and Mathematical

In statistical analysis, understanding the degree of variability in data plays a critical role in making important decisions. Two key measures commonly used to understand the distribution of such data are variance and standard deviation. Both measure how far data points deviate from the mean, but they differ in their calculation methods and interpretation. Variance and standard deviation are fundamental tools for assessing the reliability and consistency of data in engineering, scientific resear
