In a continuous choice question (eg. Very Satisfied -> Very Unsatisfied or Rating Scale) if the first choice (mean of 1) represented 100% the current means percentile relative to that is calculated and displayed.
This is especially easy when measuring data like Customer Satisfaction. If the first choice represents "Most Satisfied" and the last choice represents "Least Satisfied" then this gives an easy index for you to measure.
Note: If you have "Eliminating Choices" like "N/A" or "Other" option in a continuous variable question, please eliminate that choice by un-checking that item in the Mean Calculation.
