Data science has become a cornerstone for decision-making in industries ranging from healthcare to retail. While the workflow involves several interconnected steps, from data collection to model deployment, one step often stands out as the most critical:   Data Understanding and Preparation . Why Is This Step Crucial? Data science projects live and die by the quality of the data. The adage “Garbage in, garbage out” holds because even the most sophisticated algorithms cannot overcome poorly prepared data. Let’s explore why data understanding and preparation is pivotal: 1. Data Understanding: Gaining Insights Before Action This phase involves analyzing the data to understand its structure, quality, and potential issues. It includes: Exploratory Data Analysis (EDA):  Identifying patterns, trends, and anomalies through visualization and summary statistics. Defining Data Relevance:  Ensuring the data aligns with the problem statement. Irrelevant data can mislead the analysis. ...
