Multiple Choice

Which of the following is not a method used for determining whether data are from an approximately normal distribution?

• A) Find the interquartile range, \(\mathrm { IQR }\), and standard deviation, \(s\), for the sample. Then \(\frac { \mathrm { IQR } } { s } \approx 1.3\).
• B) Compute the intervals \(\bar { x } \pm s , \bar { x } \pm 2 s\), and \(\bar { x } \pm 3 s\). The percentages of measurements falling in each should be approximately \(68 \% , 95 \%\), and \(100 \%\) respectively.
• C) Construct a histogram or stem-and-leaf display. The shape of the graph or display should be uniform (evenly distributed).
• D) Construct a normal probability plot. The points should fall approximately on a straight line.
