Estimates variance based on a sample or population from its mean. Var. = Kurtosis characterizes the relative peakedness or flatness of a distribution compared with the normal distribution. Positive kurtosis indicates a relatively peaked distribution. Negative kurtosis indicates a relatively flat distribution.
Skewness characterizes the degree of asymmetry of a distribution around its mean. Positive skewness indicates a distribution with an asymmetric tail extending toward more positive values. Negative skewness indicates a distribution with an asymmetric tail
Range is obtained by taking the differnece between the largest and the smallest values in a data set. Returns the confidence interval for a population mean. In our research the confidence interval is set up for 95% which means we can be 95 percent confident that the population mean is in the interval:
