Exploratory Data Analysis with Python (EDA) | Descriptive Statistics | Univariate Analysis | Outlier

Exploratory data analysis (EDA) is used by data Analyst and/or scientists to analyze and investigate data sets and summarize their main characteristics, often employing data visualization methods.
It helps determine how best to manipulate data sources to get the answers you need, making it easier for data scientists to discover patterns, spot anomalies, test a hypothesis, or check assumptions.
In this video, we will use Python to carry out the EDA on AdventureWorks dataset. We will cover and see practical examples of; Descriptive statistics, Univariate, Bivariate Analysis, detect and remove Outliers and spot Anomalies.

Exploratory Data Analysis (EDA) is an approach/philosophy for data analysis that employs a variety of techniques (mostly graphical) to
. maximize insight into a data set;
. uncover underlying structure;
. extract important variables;
. detect outliers and anomalies;
. test underlying assumptions;

This video is the best out there for EDA in Python. Thank you so much. I learnt a lot with this!!

[datascience]

do you plan to add a video on Logistic Regression and Cluster Analysis in near future?
