Features Features Normal distribution is characterized by two parameters, mean (µ) and standard deviation (σ). When graphed, the mean represents the center of the bell curve and the graph is perfectly symmetric about the center. The mean, median, and mode are all equal for a normal distribution. The standard deviation measures the data's spread from the center. The higher the standard deviation, the more the data is spread out and the flatter the bell curve looks. Variance is another commonly used measure of the spread of the distribution and is equal to the square of the standard deviation.

Expert Solution & Answer

Explanation of Solution

In a nonparametric test data is not required to fit a normal distribution, in-fact, it assumes that the data does not follow any specific distribution. Whereas in case of parametric test, the data follows a normal distribution.

The information about population parameter is not available in nonparametric test.

Non-parametric test uses data that is often ordinal, meaning it does not rely on numbers, but rather a ranking or order of sorts. Parametric test uses data which is interval or ratio.

The nonparametric test is mainly based on differences in medians. Hence, it is alternately known as the distribution-free test. Whereas, parametric test uses mean as a measure of central tendency.
