DATA SCIENCE

What is Data Science?

Data Science is an interdisciplinary field that uses techniques from mathematics, statistics, computer science, and domain expertise to extract meaningful insights from structured and unstructured data. It is widely used to solve business problems and make data-driven decisions.

Key Components of Data Science

  1. Data Collection: Gathering data from various sources like databases, web APIs, or IoT devices.
  2. Data Cleaning: Removing inconsistencies, handling missing values, and preparing data for analysis.
  3. Data Analysis: Applying statistical methods and exploratory techniques to understand patterns and relationships.
  4. Machine Learning: Building predictive models using supervised, unsupervised, or deep learning techniques.
  5. Data Visualization: Representing insights through dashboards, charts, and graphs using tools like Tableau, Power BI, or Matplotlib.
  6. Big Data Tools: Managing and analyzing large datasets using tools like Hadoop, Spark, or cloud services.
