B) the static report level. C) the visual cube level. D) the self-service cube level. Answer: C Diff: 2 Page Ref: 122 37) This measure of central tendency is the sum of all the values/observations divided by the number of observations in the data set. A) dispersion B) mode C) median D) arithmetic mean Answer: D Diff: 3 Page Ref: 76 38) This measure of dispersion is calculated by simply taking the square root of the variations. A) standard deviation B) range C) variance D) arithmetic mean Answer: A Diff: 2 Page Ref: 78 39) This plot is a graphical illustration of several descriptive statistics about a given data set. A) pie chart B) bar graph C) box-and-whiskers plot D) kurtosis Answer: C Diff: 3 Page Ref: 79 40) This technique makes no a priori assumption of whether one variable is dependent on the other(s) and is not concerned with the relationship between variables; instead it gives an estimate on the degree of association between the variables.
