Hello,

I am currently working on developing a within-subject experimental research study for my Ph.D. dissertation. In the study, there will be one group where all the participants will receive all the treatment conditions. In the study, I have four display conditions of the pilot interface:

As part of the experimental task, the participants will be performing visual approaches to

four different airports, i.e., there will be a total of four different scenarios to mitigate order effects.

To mitigate the order and carry-on effect, I need to randomize the order in which each participant will recieve the display (treatment) condition and airport to perform the landing (experimental task). An a prior calculation of the sample size resulted in a total of 32 participants.

Basically, I need each participant to receive all four display conditions and perform landing at all four airports. However, I am struggling to develop a counter-balance order to assign how participants will receive each treatment condition and the scenarios in a randomized order.

Any help in figuring out this issue would be appreciated!
