Analysis Quiz

This quiz has no right and wrong answers. Instead each answer has a numeric value assigned to it and the values for the selected answers are added up to give a final total which is then converted into a percentage figure where zero percent means that the lowest valued answer was selected every time and 100 percent means that the highest valued answer was selected each time. If intermediate valued answers are selected or a mix of high and low valued answers is selected then an intermediate percentage value will result.

Step One - Fill out the following form for each question that you want to contain within your quiz. Each time you press the "Add Question" button the code in the textarea immediately below will be updated to add the new question and answers to those you have already added to the quiz. Once you have all your questions entered highlight the content of the text area and copy/paste it into a new JavaScript file (eg. quizhead.js).

Step Two - add the following code immediately before the </head> tag in the page where you want the quiz displayed.

Step Three - select the JavaScript in the following textarea and save it as quizbody.js.

quizbody.js
