Topic 1. The exploratory analysis centers around creating a synopsis of data or insights for the next steps in a data mining project. Exploratory Data Analysis is an important part of the data scientist as it helps to build a familiarity with the data we have available. It allows us to visualize data to understand it as well as to create hypotheses for further analysis. Visualization: Feature visualization is very essential to get an understanding of the data. This step is very important especially when we arrive at modeling the data in order to apply Machine learning. In this video you will learn how to perform Exploratory Data Analysis using Python. Python is a great language for doing data analysis, primarily because of the fantastic ecosystem of data-centric Python packages. It can be done in Python using stats library. Using Python for data analysis, you'll work with real-world datasets, understand data, summarize its characteristics, and visualize it for business intelligence.
