Let's Understand about Data Analytics roles!
To start with i am going ask a question? What do companies in e-commerce, entertainment, healthcare, manufacturing, marketing, finance, tech, and 100 other industries all have in common?
You guessed it, they all use data. Organizations of all kinds need data analysts to help them improve their processes, identify opportunities and trends, launch new products, provide great customer service, and make thoughtful decisions.
Hi, I'm Ravi, a data analyst myself. Maybe you're thinking about starting a career in an exciting world of data analytics, or maybe you're just fascinated by the power of data, as I am. No matter what you hear, you're in the right place to know about data analytics.
But first, what exactly is data? What I like to say is that data is a collection of facts. This collection can include numbers, pictures, videos, words, measurements, observations, and more. Once we have data, analytics puts it to work through analysis.
Data analysis is the collection, transformation, and organization of data in order to draw conclusions. Make predictions and drive informed decision-making. And it doesn't stop there. Data evolves over time, which means this analysis, or analytics as we call it, can give us new information.
Data is everywhere. It used and created it every day. Have you ever read reviews of a product before deciding whether or not to buy it? That's data analysis. Or maybe you wear a fitness tracker to count your steps so you can stay active throughout the day. That's data analysis. But you don't just use data; you also create huge amounts of it every single day. Anytime you use your phone, look up something online, stream music, shop with a credit card, post on social media, or use GPS to map a route, you're creating data. Our digital world and the millions of smart devices inside of it have made the amount of data available truly mind-blowing.
At Google, we processes more than 40,000 searches every second. That's 3.5 billion searches a day and 1.2 trillion searches every year. Here's another way to think about it. YouTube has almost two billion users. If YouTube users made up a country, it would be the largest in the world. All of that data is transforming the world around us.
The publication “The Economist” recently called Data, the world's most valuable resource. So it's easy to see why data analysts are so valued by their organizations. And what exactly does a data analyst do?
Put simply, a data analyst is someone who collects, transforms, and organizes data in order to help make informed decisions. Besides the role itself, one of the most exciting parts of being a data analyst is the number of opportunities available. The demand for data analysts is greater than the number of qualified people to fill these job openings.
Data analysts come from many different backgrounds and have all kinds of life experiences. You don't need decades of work experience or an expensive education to get started. Many data analysts taught themselves the skills they needed to land their first job, just like you're doing right now.
Any data analytics should follow the below process for analyzing any data.
Those are (APPASA)
Ask. Prepare, Process, Analyze, Share, and Act. Each one covers a new topic, and every topic builds on what you've learned before.
I truly believe that cleaning and modeling data is the heart and soul of data. It's how you get to know your data. It's quirks, it's flaws, it's mysteries.
Data analysis is the collection, transformation, and organization of data in order to draw conclusions, make predictions, and drive informed decision-making.
