Which of the Following Is Not a Method Used for Determining

question 36

Short Answer

Which of the following is not a method used for determining whether data are from an approximately normal distribution? A) Construct a histogram or stem-and-leaf display. The shape of the graph or display should be uniform (evenly distributed).
B) Compute the intervals $\bar { x } \pm s , \bar { x } \pm 2 s$ , and $\bar { x } \pm 3$ . The percentages of measurements falling in each should be approximately $68 \% , 95 \%$ , and $100 \%$ respectively.

C) Find the interquartile range, $\mathrm { IQR }$ , and standard deviation, $s$ , for the sample. Then $\frac { \mathrm { IQR } } { \mathrm { s } } \approx 1.3$ .

D) Construct a normal probability plot. The points should fall approximately on a straight line.
