TESTS RANDOMISATION:

To minimise bias in metallurgical testing, it is common practice to randomise the tests of different conditions.
Each test condition/variation should also be repeated a number of times (example in triplicate) to assess the reproducibility.
This tool is very handy in randomising such tests of different conditions.

To use:

Enter the tests variations (the first test variation will be listed first).

Provide the number of repeat tests for each test variation (e.g.: 3 for triplicate tests).

Click on "Randomise tests" to come up with a randomised tests list.

An example can be seen on this Youtube video.
