[ARCHIVED] Do quiz formula question support greater than or equal >=

[lherdan]

An instructor would like to use the formula below in quiz formula question.

if abs(zscore) > = 3

This results in an unrecognized token error. Can you use "> =" with the formula question? It would be helpful to know what functions are not supported in a formula question. Instructors want to use expressions that work in Excel, but from my experience Canvas is not as robust.

Hello @lherdan 

We might need further information on this. I was able to play around with the Equation editor in the RCE and I found that you can insert "> =" with the editor. The = option can be found on the basic area of the Equation editor. The > sign can be found on the Relationships screen in the editor. 

I am not super familiar with using excel and how it makes the expressions in those programs. 

I was able to find this GUIDE on using the Math Editor in the RCE. 

HERE is a PDF on doing basic Equations.

Hi @ColtonSwapp 

The RCE isn't available for the Formula Definition field. This is where you type the formula and where the instructor wants to use the symbols.

Thanks,

@lherdan I believe that the issue being encountered by the instructor when trying to use the formula: if abs(zscore) > = 3 in a formula quiz question is the number of arguments in the if statement.  When if is used in the formula quiz, it takes three arguments: the boolean (abs(zscore)>=3 in this case), a success value, and a fail value.  Since the if is missing two condition, the token error arises.  

More detail on using formula quiz questions can be found in How do I create a Formula quiz question with a single variable? but I believe the Canvas Formula Quiz Question Helper Functions PDF documentation will be of even more assistance on this issue.
