That is a bad designed test, for all the reasons you learn in psychology when talking about experimental test design.
Most importantly: How is this thing scored? Imagine you have everything but one block in the right order. Now every element following that false positioned block is one apart from the right position. Are they now wrong as well? Or are they scored as correct as they are in the correct order in itself?
I'm sure there exists rules for this test design, but it is a hard decision nonetheless. It's error-prone.
It would be a way more sound experiment when presenting always only two colour blocks and letting the user bring them in order (or let them decide: which one is greener, stuff like that). This way one would also detect whether people are able to distinguish between the colours.
Edit: But if they are specific testing for the way people arrange that stuff and try to detect patterns, then well, might be a different story.
- sudont 13y agoMost likely you could score with a levenshtein distance. http://en.wikipedia.org/wiki/Levenshtein_distance http://en.wikipedia.org/wiki/Levenshtein_distance
- onli 13y agoGood idea. Well, it all depends what you want to test. Normally, such an experiment should try to detect which colours when compared can still be distinguished, detecting the smallest notable difference/patterns which don't work for subgroups. I don't see how that could work well with the measurement. If it really is about the whole row of colours, then the levenshtein distance could indeed work well.
- nilkn 13y agoIt seems this would not fix the issue of having one block off and thereby pushing a bunch of other blocks one off from their right position. You'd still have to move all those blocks back, which means the Levenshtein distance would not be short.
