Random allocation block (n=3) method is used to allocate the individuals to the control and intervention groups.
In this case, three blocks were determined with the help of the random numbers table. For each selected number, which was between 0-4, the ABC and if the number was 5 - 9, we write the term BCA and 10 – 14 CAB, together with each other as a string. For example, if the numbers selected are 7, 4, 6, 11, 14 and 3, the terms are: BCA - ABC - BCA - CAB - CAB - ABC.
Thus, the first child in Group B (the Aromatherapy) and the second in Group C(Control) and a 3th , 4th in Group A ,5th in Group B and sixth in C and the7th in group B, eighth in Group A and the 9th in Group A and the 10th case in group C Will continue as well as the sample size is sufficient.
