Basic Online Form with Basic Statistical Formulas in Database

I need a basic online form with a sign up fields plus about 30 multiple choice questions. The form should be linked to a database that has basic statistical formulas e.g. Average, Weighted Average, Standard deviation and Z-Score to analyze each of the multiple choice answers entered by users and also overall for each user. When a signed up user logs in they can view how others answered the questions [i.e. Average, Weighted Average, Standard deviation and Z-Score ] and also the top 10 users with answers that were closest to their own answer choices. ## Deliverables * * *This broadcast message was sent to all bidders on Sat.
