Hey everyone,

I'm relatively new to LimeSurvey. Is there a way I can disqualify respondents based on how they rank numbers in a Ranking Type R question? I have a question set up that asks participants to rank the numbers 1 to 10 from smallest to largest number. I'm trying to use it as an attention check/bot deterrent!

Some additional info; I'm using version 6.4.3 and I'm using my own server.

Any help is appreciated!

Hi,
you screen out these participant with a quota.
To get a handy criterium  you create a question of type equation, which you use IN your quota.
One easy way is (of course you use numeric codes in your ranking question ("rank")) to check if
code 1 is on 1st rank
code 2 is on 2nd rank
code 3 is on 3rd rank
and so on
{if(rank_1==1 and rank_2==2 and rank_3= and ...and rank_10==10 ,1,0)}
So if the result is "0" the participant did not answer correctly.

A different and shorter equation might be
{if(join(that.rank)=="12345678910",1,0)}

And read the manual about equations, implemented functions and the variables "self", "that"

{if(join(that.rank)=="12345678910",1,0)}

That is a good one! I like how you solved that.
