For randomization, the permutation random blocking method is used. In this method, 14 blocks of 4 from a combination of letters A and B will be randomly selected. These blocks are AABB, ABBA, BBAA, BAAB, ABAB, BABA. The blocks are selected in such a way that the following numbers are assigned to the blocks:
1:AABB
2:ABBA
3:BBAA
4:BAAB
5:ABAB
6:BABA
Then 14 one-digit random numbers are selected from the table of random numbers. If the number 7 8 9 is among these digits, they will be deleted. In this way, 14 blocks are selected. Assigning the letters A and B to the intervention and control groups will be done randomly before randomization and the data analyst will be unaware of the intervention and control groups. Having a list of people (a list of 56 people who are going to participate in the project), the researcher assigns a numeric code to each person. It then provides the anonymous list of members (containing only the numeric code) to the sample assignor to the groups. The sample assignee to the groups first prepares the selected blocks as described, writes them on separate sheets of paper (14 separate sheets), and places them in sealed envelopes. It then randomly selects the envelopes and, based on the previously selected codes A and B, determines the numerical code number of the individuals assigned to intervention A and B and provides it to the researcher. For example, if the BABA block is selected first, the first person on the list will be assigned to group B, the second person to group A, the third person to group B, and the fourth person to group A. Similarly, person 5 to 56 will be assigned to groups A and B.
