Professor wanted a set of questions about X, another set of Y, and a set of Z but he wanted them to be randomized so first student gets X-Y-Z, the second gets Y-X-Z, the third gets Z-Y-X, etc. For example:
Student 1 | Student 2 | Student 3 |
Set X Q1 | Set Y Q1 | Set Z Q1 |
Set X Q2 | Set Y Q2 | Set Z Q2 |
Set X Q3 | Set Y Q3 | Set Z Q3 |
Set Y Q1 | Set X Q1 | Set Y Q1 |
Set Y Q2 | Set X Q2 | Set Y Q2 |
Set Y Q3 | Set X Q3 | Set Y Q3 |
Set Z Q1 | Set Z Q1 | Set X Q1 |
Set Z Q2 | Set Z Q2 | Set X Q2 |
Set Z Q3 | Set Z Q3 | Set X Q3 |
We set up separate pools for X, Y and Z and then created a test using Questions Set and randomized the question order for the test overall. It randomized the X-Y-Z, Y-X-Z, Z-Y-X as expected AND it also randomized within the sets:
Student 1 | Student 2 | Student 3 |
Set X Q2 | Set Y Q3 | Set Z Q1 |
Set X Q3 | Set Y Q2 | Set Z Q3 |
Set X Q1 | Set Y Q1 | Set Z Q2 |
Set Y Q1 | Set X Q2 | Set Y Q1 |
Set Y Q2 | Set X Q3 | Set Y Q2 |
Set Y Q3 | Set X Q1 | Set Y Q3 |
Set Z Q3 | Set Z Q1 | Set X Q2 |
Set Z Q2 | Set Z Q2 | Set X Q3 |
Set Z Q1 | Set Z Q3 | Set X Q1 |
I'm sure this is considered Functioning As Designed and it's helpful for most situations but in this case the order within the sets mattered so close but no cigar for him. I even tried using separate tests rather than pools to see if the order was retained but it wasn’t.
