Foundation of Data & Business Context

Introduction to Data Analysis is the process of collecting, organizing, cleaning, and interpreting data to discover useful insights, identify patterns, and support decision-making. It involves using statistical techniques, analytical tools, and visualization methods to transform raw data into meaningful information that can help individuals and organizations solve problems, make predictions, and improve performance.

Data can exist in various forms, including numbers, text, dates, images, and categories. Before analysis begins, data must be properly identified and structured to produce accurate results.

Business metrics are measurable values used to track, monitor, and evaluate the performance of a business, department, process, or activity.
