In this module, you will work with customer data and transaction data to prepare them for advanced analysis. You will begin by analyzing the data set to identify key fields and understand its structure. Next, you will clean the data by removing duplicates, handling missing values, and correcting inconsistencies using Excel. During the transformation phase, you will create new data fields and categorize information to uncover customer segments and transaction patterns. Additionally, you will focus on visualizing the data to extract actionable insights. You will use Excel’s charting tools to create bar charts, line graphs, and pie charts. To ensure all tasks are completed accurately, each lab includes a checklist, which verifies that you have completed all essential steps.
