Data Vizualisationsfinding what item is sold the maximum out ofthe others Test data preparation Problem statement:The data scientists at BigMart have collected 2013 sales data for 1559 products across 10 stores indifferent cities. Also, certain attributes of each product and store have been defined. The aim is tobuild a predictive model and find out the sales of each product at a particular store.Scope:Using this model, BigMart will try to understand the properties of products and stores which play akey role in increasing sales.
