We considered the number of samples in each block to be twice the number of groups, considering that the sample volume was equal to 120 people, for this purpose, 15 envelopes were prepared and we named them in order from number 1 to 15. Each envelope had eight identical cards. . Two cards were randomly assigned to each group and group labels with letters A, B, C and D were inserted on them.
