Background of Data Science
Data Science combines statistics, computer science, and domain knowledge to analyze structured and unstructured data. Its evolution stems from:
-
Statistics (1900s): Foundations in hypothesis testing, regression analysis, and sampling.
-
Computer Science (1960s–1980s): Database systems, programming languages, and machine learning foundations.
-
Big Data Era (2000s–Present): Explosion of data from IoT, social media, and cloud computing.
The term “data science” emerged as the bridge between raw data and actionable insights, turning information into real-world decisions.
Today, data science has evolved beyond analytics into an interdisciplinary powerhouse that fuels artificial intelligence, business intelligence, and predictive systems that can shape entire industries.
Key Components of Data Science
To understand the full archive of data science, let’s break down the core stages:
-
➡️Data Collection – Gathering raw data from APIs, databases, sensors, logs, and user interactions.
-
➡️Data Cleaning – Handling missing values, duplicates, outliers, and inconsistencies.
-
Data Analysis – Applying statistical methods, hypothesis testing, and exploratory data analysis (EDA).
-
Machine Learning – Building predictive and prescriptive models using supervised, unsupervised, and reinforcement learning.
