How do I figure out what a coding method for variables in Data Analytics is? I have been given 8 variables and have to figure out the coding method. The variables I have been given are:

V1: Shopping is fun;

V2: Shopping is bad for your budget;

V3: I combine shopping with eating out;

V4: I try to get the best buys while shopping;

V5: I don't care about shopping;

V6: You can save lot of money by comparing prices;

Income: The household income of the respondent;

Mall Visits: The frequency of mall visits.

The question I have to answer is: What is the coding method for the above variables?
