Qtype-Formula - Combine a calculation answer with MCE

Hello everybody,

I hope you are well and have peace in your heart!

Please, I would like to ask for help in the following situation:

1- I have 4 questions that calculate the elasticity of demand for 4 products.

2- Demand elasticity can be of 3 types:

If elasticity is < 1, then we have inelastic demand

if the elasticity is = 1, then we will have unit demand (unit elasticity)

If the elasticity is > 1, then we will have elastic demand

I would like that on the side of each calculation for each elasticity, there was an MCE, with these 3 possibilities: inelastic - unitary - elastic.

Thus, after the calculation, according to the value, the student could choose the type of elasticity they found in the calculation.

It would be possible?

Thank you very much, Marcelo.

It has been a while since I did something similar, but I think you should be able to do what you want with the Formulas question type. https://moodle.org/plugins/qtype_formulas

Dear Al Rachels,

Thank you very much for your return.

You are sure! I was able to perform the combination using operators.

Thank you very much!

Marcelo.

Hi Marcelo,

the usage of MC is well descriped on Dominique's site dynamiccourseware.org .
The multichoice answers are put in an array:
       MCA = ["inelastic elasticity","unit elasticity","elastic elasticity"];
Depending on the results for e1, ... it must decided which element of the array is the right answer. So it is a nested IF:
       help = (e1 < 1) ? 0 : ( (e1==1) ? 1  :2 );    
As mentioned the result must be a number (in this case  0,1, or 2).
In parts text you have two possibilities:
Radio buttons:  {_0 : MCA} or a
dropdown menue: {_0 : MCA : MCE} !
(To my knowledge multiple answers are not possible!)

Find the question attached!

Cheers

Joachim

Hi Joaquim,

I hope you are well and at peace! 

I apologize for the delay in getting back to you. 

This strategy worked well. 

Thank you very much for helping me once again! 

Thank you very much! 

Marcelo.

Note: Thank you very much for the valuable explanations in your comments within the question - in the variable items. Explanations are extremely important to me!
