May 2025 DataDNA – Mobile Phone Sales
You are a data analyst for a major mobile phone retailer operating across multiple countries. You’ve been given a 2024 sales dataset, containing detailed records of mobile phone transactions, customer demographics, product specifications, and geographic locations. The dataset combines information about the models sold, their prices, storage sizes, colors, operating systems, and customer demographics like age group and gender. It also captures where and how the sales were made – online, through partners, or in-store, and the type of payment used.
Your goal is to build a report that tells the story of mobile sales across different regions, highlights best-selling products and trends, and helps the business understand customer behavior better.
