Exploratory Data Analysis (EDA) in Data Science
Exploratory Data Analysis (EDA) is a crucial step in the data science process that involves analyzing and visualizing data to gain insights and identify patterns. It serves as the foundation for understanding the characteristics of the dataset and informing subsequent analysis and modeling decisions. In this article, we will explore the principles, techniques, and best practices of EDA in data science. Understanding Exploratory Data Analysis EDA is an iterative process that begins with obtaining the dataset and ends with a deeper understanding of its underlying structure and relationships. The primary goals of EDA include: Data Cleaning : Identifying and handling missing values, outliers, and inconsistencies in the dataset. Descriptive Statistics : Calculating summary statistics, such as mean, median, standard deviation, and percentiles, to describe the distribution of the data. Visualization : Creating visual representations, such as histograms, scatter plots, and box plots, to expl
