... mean value. There will be some ‘error’ as the mean value from one sample is not likely to be exactly the same as the population mean. We need to report the ‘confidence interval’ of the estimated mean value, to acknowledge the degree of uncertainty we have regarding where the population mean may be. ...

Chi-Square Test
... The Anderson-Darling (A-D) test is based on a probability plot. When the data fit the hypothesized distribution closely, the probability plot will be close to a straight line. The A-D test is widely used because of its power and attractive visual. ...
