How to Learn Tableau Top Tips

As the world gets more globally connected, we see massive amounts of data generated at every turn. Companies large and small work with data to gain insight and make critical business decisions. For this data to be useful, however, it must be properly analyzed. Data analysis involves taking raw data and adding it to user-friendly data visualization dashboards.

 

What’s Data Visualization? 

Data visualization is the process of representing data in the form of a graph, chart, or any other visual format. This makes it easy to understand the information depicted in the data. It is easier for a human brain to grasp the information that is depicted pictorially instead of lumps of data that is unstructured. Data visualization is one of the most important processes involved in data analysis.

 

Can you even make a guess on how much data is generated every second? A report by SiliconAngle says that there would be 20 billion smart devices connected to the Internet and the amount of data generated can be baffling. It is expected that 463 exabytes of data will be generated each day worldwide, by 2025. Some of the daily key stats in the same report state that 294 billion emails are sent, 5 billion searches are made, 500 million tweets are made daily.

 

Where is Data Visualization Used?

Clearly, data visualization is crucial for managing these massive amounts of data, so that a non-analyst can understand the data quickly. Data visualization powers decision making by answering some important questions like “what are the relationships and trends?”; the presence of outliers, comparison of different values over different periods, or what trends are depicted by the datasets.

 

Weather maps, real-time air-quality indices, annual income, and expense report spreadsheets, and Facebook page statistics are examples of data visualization. It is used in many other ways to help stakeholders make quick decisions.

 

This article will let you understand how important and rewarding it can be to make a career in this domain. If you look forward to making a career in data visualization, taking up the Tableau Desktop Specialist Certification exam can be a smart move.
