Big Mart outlet sales prediction

Is there a relationship between item visibility and sales?¶

The data scientists at BigMart have collected 2013 sales data for 1559 products across 10 stores in different cities. The main objective is to understand whether specific properties of products and/or stores play a significant role in terms of increasing or decreasing sales volume.

Goals in this analysis:

• Impute any missing string or numerical values
• edit any extraneous or misspelled categorical values (low fat, Low Fat, low phat)
• Calculate the actual ‘age’ of each outlet
• gain insight on the relationship between item visibility and sales of each outlet
