Data science encompasses a wide range of techniques and processes to extract insights and knowledge from data. Here are some basic points that capture the essence of data science:

Data Collection:
Gathering relevant data from various sources, including databases, sensors, websites, and other repositories.

Data Cleaning and Preprocessing:
Addressing missing values, handling outliers, and preparing data for analysis by transforming and cleaning it to ensure accuracy and reliability.

Exploratory Data Analysis (EDA):
Examining and visualizing data to understand its characteristics, patterns, and relationships. EDA helps in forming hypotheses and guiding further analysis.
