Radio button calculations
October 4, 2013 12:00 AM
Hi, I am creating a survey where there are 3 radio button sets that need to be averaged and then presented in a text field as a rounded whole number. The button names match the labels. It would work like this (the lowercase o represent the radio button):
Question 1
o 0
o 1
o 2
o 3
Question 2
o 0
o 1
o 2
o 3
Question 3
o 0
o 1
o 2
o 3
Results:
Average score = X
I tried to set the result variable X to this: var(Question1)+var(Question2)+var(Question3)
Instead of a sum, I am getting: "1+2+3" in the text field. I'm sure it is treating the numbers as strings, I just don't know what to do about it. I haven't gotten to trying to average them or round them into whole numbers.
Is this possible with radio buttons?

OK, I found a long winded solution of selecting the Add to Variable type in the Modify Variable action and adding each sub variable separately. Lastly I used the Divide Variable By and Round Variable types. The good news is I didn't have to convert any text to numbers. The Round Variable Type is quite handy.
It's possible when using the "old" way and adding each Question variable to a "result" variable with a separate action.
