Bekky's Place Online store is a supermarket that sells all varieties of items in different categories, from Fashion to Home and Office supplies.

They have got a dataset of their shopping over 5 years, from 2015 to 2020. The CEO, Miss Ahmed Oluwaseunfunmi Eberechukwu would like to see how the supermarket is fairing by certain Key Performance Indicators. The manager, Mr Idara Ogunyele Sabo has been assigned the task to identify the key areas within the business that need clarification and get them sorted out as soon as possible.

Mr. Idara decided to recruit Ayodele as a Data Analyst to analyze the sales dataset and come up with results and visualization.

Tasks

  1. Total revenue by product category.
  2. Reasons why customers return some of our items.
  3. Revenue by YoY.
  4. Customers' gender by percentage.
  5. Which of our delivery channels have the biggest revenue by percentage?
  6. Percentage of revenue by gender across age groups.
