A theoretical distributionthat has the stated characteristics and can be used to approximate many empirical distributions was devised more than two hundred years ago. It is called the “normal probability distribution,” or the normal distribution. It is sometimes called the Gaussian distribution. Proba...
All parametric tests are based on normality; hence, it is essential to understand the normal distribution and its characteristics. Skewness and kurtosis are the two benchmarks for understanding distribution of data. Using these characteristics, one can describe the nature of research data and draw ...

Sometimes it is also referred to as "bell-shaped distribution" because the graph of itsprobability density functionresembles the shape of a bell. As you can see from the above plot, the density of a normal distribution has two main characteristics: it issymmetric around the mean(indicated by t...

What Is the Normal Distribution? The normal distribution formula is based on two simple parameters—mean and standard deviation—that quantify the characteristics of a given dataset. While the mean indicates the “central” or average value of the entire dataset, the standard deviation indicates ...
