Calculating mean/average in form
Good morning!
I am working on converting paper assessments into a digital form that can be used online. At the end of the assessment, the teacher circles a number in 4 categories. They then add the numbers and find the mean.
I've set my form up to have 4 groups of radial buttons, labeled Choice1, Choice2, Choice3, Choice4, Choice5. How would I calculate the mean of those 4 groups? Does anyone know a JavaScript formula or is there a way to do it in the form?
Thanks in advance.
