Work Step by Step
There are 20 volunteers who are numbered as and divided into two groups of 10 volunteers. The names of the volunteers along with the numbers assigned to them are shown in the table.
The volunteers in the experimental group are chosen using the random number table provided in the book. The two-digit random numbers are chosen from the random number table starting from the first row and the first column of the table. The random number is selected between 01 and 20 and if the same random number is repeated, it is rejected. If the selected number is 00 or more than 20, then that number is also rejected. The selected random numbers are .
The individuals selected for the experimental group are the volunteers who are numbered with the same number as the random numbers obtained from the random number table.
Therefore, the volunteers of the experimental groups are Tom, Shannon, Marissa, Julia, Kevin, Joe, Colleen, Sue, John, and Wanda. The rest of the volunteers are assigned to the control group.
