1. Introduction to Data Science
Data Science is an interdisciplinary field that uses scientific methods, algorithms, and systems to extract insights and knowledge from structured and unstructured data. It combines skills from statistics, computer science, and domain expertise to solve complex problems.
Key Components:
- **Data Collection**: Gathering data from various sources, such as databases, surveys, and web scraping.
- **Data Cleaning**: Removing errors and inconsistencies in the data to ensure accuracy.
- **Data Analysis**: Applying statistical methods to explore and analyze the data.
- **Machine Learning**: Using algorithms to create predictive models based on historical data.
- **Data Visualization**: Presenting data insights visually using graphs, charts, and dashboards.
