What Is Data Science?

Lesson 1: What Is Data Science?

Lesson 1: What Is Data Science?

Data Science is an interdisciplinary field that focuses on extracting meaningful insights from data. It combines concepts from:

Statistics and Mathematics
Programming and Computer Science
Domain knowledge

A typical data science workflow includes:

Data Collection: Gathering raw data from sources such as files or databases
Data Cleaning: Handling missing values and correcting data types
Exploratory Data Analysis (EDA): Identifying patterns, trends, and distributions
Feature Creation: Creating new useful columns for analysis
Insight Generation: Interpreting results to support decision-making

In this project, data science techniques are applied to sales data to analyze historical records and understand business performance. The focus is on analysis and insights, not prediction.
