These figures of data science vs data analytics salary, influenced by experience and location, highlight the growing value of data professionals in the country's tech landscape. Through this blog, Let us know more deeper about the what is data science vs data analytics :
Definition and Scope of Data Science
What is Data Science?
At its core, data science is an interdisciplinary field that seeks to derive meaningful insights from large and complex datasets. It encompasses a range of techniques from statistics, computer science, and information theory to analyze, interpret, and represent data. The scope of data science goes beyond mere analysis; it covers the creation of data models that can predict the future or classify unseen data points.
Core Components and Processes of Data Science:

1. Data Collection & Cleaning
- Collection: The process begins with gathering raw data from various sources, be it sensors, user inputs, databases, or external data sources.
- Cleaning: Raw data often contains errors, missing values, or outliers. Cleaning ensures that data is accurate, consistent, and usable. This step often takes up a significant portion of a data scientist's time but is crucial for the accuracy of subsequent stages.
2. Data Exploration & Experimentation
- Exploration: This involves diving deep into the data to identify patterns, correlations, and anomalies. Techniques like data visualization and statistical analysis play a pivotal role here.
- Experimentation: Once initial insights are gathered, hypotheses are formed and tested. This iterative process aids in refining the insights and preparing for modeling.
3. Machine Learning & Predictive Modeling
- Machine Learning: It's an application of AI that allows systems to learn and improve from experience without being explicitly programmed. In data science, ML models are trained on data to make predictions or decisions.
- Predictive Modeling: This is about forecasting future outcomes based on patterns in the data. It can range from predicting stock prices to determining the likelihood of a patient's illness in healthcare.
