3.5 Automating the task

In a class of 30 students, the number of combinations to consider is = 435, you probably don’t want to do this by hand! It is, therefore, best to use a spreadsheet or a program to do this.

3.5.1 Capturing the data

First, use a worksheet to enter the choices made for each question for each student. I usually use a row for a student, and use a column for each question/feature.

3.5.2 Computing the probabilities

This is best done by a program. Export the data captured in the previous step to a comma-delimited format, and use a program to read that and perform the analysis.
