INTRODUCTION

In today’s data-driven world, data is at the heart of everything we do. Whether it's business, healthcare, technology, or any other field, the ability to understand and analyze data has become increasingly essential. If you're considering a career in data analytics, it's crucial to have a deep interest in data, a willingness to learn, and a passion for uncovering insights hidden within vast datasets.

This guide will walk you through the fundamentals of data analytics, providing you with the knowledge and tools you need to succeed in this exciting field. But first, let’s start with a clear definition.

definition Data analytics involves using data, techniques and tools that identify patterns and trends to generate insights that support decision making. Data analytics extracts actionable insights from data to enable organizations, companies to make informed decisions.

Fundamentals Of Data Analytics

Data analytics relies on four fundamental processes to ensure effective analysis. These processes, outlined below, are essential for deriving meaningful insights from data.

Data Collection: Involves getting data from different places such as websites, survey or business records.

Data cleaning: This process involves cleaning up data by handling missing values, duplicated values, and putting the data in order so it's easier to look.

Analyzing the data: This involves using math and computer programs to find patterns, trends, or interesting in the data. This includes creating charts, graphs, performing statistical summaries.

Making decisions: Understanding what the data tells us and using the information to make choices or plan what to do next.

Types Of Data Analytics
There are mainly 4 types of data analytics in which each answer a key question about your data's journey;

• Descriptive Analytics: Looks at past data to tell you what happened before.
• Diagnostic Analytics: This analytics tries to figure out why something happened.
• Prescriptive Analytics: Suggests what you should do based on the data analysis.
• Predictive Analytics: makes predictions about future outcomes using historical data combined with statistical modeling, data mining techniques and machine learning.
