... Two or more individual statistical functions can be combined to compute additional descriptive numerical measures. Four of these commonly presented in business statistics textbooks include the coefficient of variation, the interquartile range, Pearson’s coefficient of skewness and the box plot. The ...

... SY2 X is not systematically affected by direct selection, but SY2 is reduced by direct selection. Therefore r 2 must be reduced by direct selection and bZ r must be smaller in the selected sample. Therefore (b) is correct. 17. b Option (b) is correct because power is lower when the Type I error ...

... If skewness = 0, the data are perfectly symmetrical. But a skewness of exactly zero is quite unlikely for real-world data, so how can you interpret the skewness number? In the classic Principles of Statistics (1965), M.G. Bulmer suggests this rule of thumb: ...
