Top 5 Websites to Obtain Datasets for Your Data Science Projects

Introduction

In the life cycle of any Data Science project, it begins by understanding the requirements and objectives of the business problem. In this phase, it is essential to have knowledge about the problem to be solved, ask the right questions, and define the horizon where you want to go.

Having completed its initial phase, we can start with the fun part: data acquisition!!

What is Data?

Data are all the information extracted from reality, which is recorded in some physical or symbolic support. It implies a conceptual elaboration and must be expressed in some form of language.

Pro Tip: Remember the famous phrase, “Garbage in, garbage out” - the quality of your work will largely depend on the quality of your data.

Top 5 Data Sources
