Data Analytics—What is it? A Guide for Complete Beginners

Nowadays, we are living in a digital age where everything is based on data, and it only keeps growing. However, raw data by itself has no value until it is analyzed and converted to actionable insights. That is where data analytics enters the picture.

Whether you are getting into the field or simply interested in how data can help you make better decisions, this guide will provide you with all the knowledge you need to become a data-savvy decision maker.

What is data analytics?

Data analytics involves analyzing raw data to find patterns, trends, and insights that can be used in decision-making. It entails gathering, cleaning, and analyzing data to solve problems or identify opportunities.

Organizations use data analytics to track customer behavior, enhance products, reduce costs, and even predict future trends.

Data Analytics vs. Data Science

• Data Science: Uses advanced techniques like machine learning to make predictions or build intelligent systems.

Think of data analytics as answering “What has happened?” and data science as forecasting “what will happen next?”

Types of Data Analysis

• Descriptive Analytics: What has occurred? (e.g., monthly sales reports)
• Diagnostic Analytics: Why did it happen? (e.g., drop in sales)

• Prescriptive Analytics: What should we do? (e.g., optimizing delivery routes)
