Hello,
I am doing a survey to collect information about student's daily commute to the university and see if they are willing to participate in a carpooling program if it was to be implemented. I want to show them a table just as the one attached. However, my problem is that I want each student to get a different scenario by random. For example, for the doo-to-door travel time, I want to give different levels (10%, 20%, or 30% increase in travel time compared to the private car). So how can I define my levels and randomize the scenarios? Also, the door-to-door travel time is not a constant that I should put; however, the student should answer a question at the beginning of the survey about it. Meaning that, if a student answers that it takes him 30 mins to reach to campus using his private car in the previous question, then the door-to-door travel time given to him using app-based carpooling will be the value he entered multiplied by a random level (30mins*30% increase). So, how can I refer to his answer in the table to be added as the door-to door travel time using a private car?
I appreciate your help or any guidance on this!
