![]() ![]() It’s a method of data analysis that automates analytical model building. Machine Learning (ML) is a subset of Data Science. What is the difference between Data Science and Machine Learning? It can be applied to diverse fields like healthcare, social sciences, and technology. Data Science has a broader scope, encompassing various data types and sources, not just business-related data. It’s more specific to business-related problems like costs, profits, and market trends. What is the difference between Data Science and Business Analytics?īusiness Analytics is primarily concerned with analytics that provide insights for business growth and operations. Data Science, on the other hand, emphasizes algorithms and machine learning models to make predictions and decisions without human intervention. It’s more about data processing and performing statistical analysis on existing data datasets. Analytics often seeks to provide a solution to a specific question. While both fields aim to derive insights from data, their scope and focus differ. What is the difference between Data Science and Data Analytics?ĭata Analytics is a subset of Data Science. ![]() While BI answers the “what happened?” question, Data Science answers “why did it happen?” and “what could happen next?”. It not only looks at the past but also predicts future events (predictive analytics) and prescribes actions (prescriptive analytics). Data visualization tools and dashboards are common in BI to represent this information.ĭata Science, in contrast, delves deeper. It uses historical data to identify trends, analyze the causes of events, and interpret past results. BI primarily focuses on descriptive analytics, and data reporting which is about understanding past events. Data Science versus Business Intelligenceīusiness Intelligence (BI) and Data Science often overlap but serve different purposes. A Data Scientist combines domain expertise, programming skills, and knowledge of mathematics and statistics to extract actionable insights from data. Think of Data Science as the entire ocean, while a Data Scientist is a skilled diver exploring its depths. On the other hand, a Data Scientist is an individual who practices these techniques. Other Fields Data Science versus Data Scientistĭata Science, as a field, encompasses a broad range of techniques and methodologies used to analyze and interpret complex data. A good data scientist is not only technically skilled but also curious, skeptical, and has a knack for storytelling. It’s essential to understand that Data Science is not just about the techniques but also about the mindset. As new training data becomes available, models are refined, leading to better insights and more informed decisions. Iterative Refinement: Continuously improving the model based on new data and feedback.Deployment: Implementing the model in a real-world environment.Evaluation: Assessing the performance of the model.Modeling: Applying algorithms to the data to make predictions or classifications.Feature Engineering: Transforming data to improve the performance of machine learning models.Data Exploration: Using statistical methods to understand the nature of the data and identify patterns.Data Cleaning: Processing the data to remove any inconsistencies, errors, or redundancies.Data Collection: Gathering raw data from various sources, which could be databases, sensors, or user inputs.This process often involves several steps: The Basic Principle Behind Data Science TechniquesĪt the heart of data science lies the essential process of data summarization, which allows professionals to quickly grasp the fundamental characteristics of vast datasets. What is Data Science - Lifecycle, Applications, Prerequisites, and Tools 2įigure 1: The Data Science Venn Diagram by Drew Conway, showcasing the intersection of Hacking Skills, Math & Statistics Knowledge, and Substantive Expertise. Data Science is the art and science of turning this vast amount of raw data, into actionable insights. From the choices we make online to the sensors in our smartphones, data is everywhere. In the age of information, businesses, governments, and individuals produce and consume an unprecedented amount of data. It’s not just about analyzing vast amounts of often unstructured data it’s about making that data tell a story and inform decision-making. Introduction to Data Science Definition and Overviewĭata Science, often hailed as the “sexiest job of the 21st century” by the Harvard Business Review, is an interdisciplinary field that leverages techniques from statistics, mathematics, and computer science to extract insights and knowledge from structured and unstructured data. ![]()
