The subjects in this study should be numbered using numbers from . Using a table of random digits, the researcher should work from left to right starting with the first row and first column to select numbers, select values that are in the correct range, and skip repeating numbers. The subjects whose numbers correspond to the randomly generated numbers are assigned to group A. The remaining subjects are assigned to group B.
There are 60 subjects, so number them from 01 through 60. Using two-digit labels makes it easy to read pairs of digits from the random-digit table; keep values in that range and skip repeats. Choice B, 01–60, is the correct numbering range.
