Difficulty implementing EDA



Recently, I was suggested to have practical knowledge on EDA through the case study BigMart Sales Prediction using R. But I cannot decide which variables should I choose for univariate, bivariate and multivariate analyses so that my analysis is focus only upon the business problem.

I tend to use up all the variables and then get confused upon which visualisations answers to the business problem(s). Is there any hidden methodology/thumb rule/sequence which should be followed in this matter?


There is no thumb rule. Try to learn from others work and of course practice a lot. You will surely get better at it.
