Показать описание
The preliminary analysis of data to discover relationships between measures in the data and to gain an insight on the trends, patterns, and relationships among various entities present in the data set with the help of statistics and visualization tools is called Exploratory Data Analysis (EDA).

Exploratory data analysis is cross-classified in two different ways where each method is either graphical or non-graphical. And then, each method is either univariate, bivariate or multivariate.

Uni means one and variate means variable, so in univariate analysis, there is only one dependable variable. The objective of the univariate analysis is to derive the data, define and summarize it, and analyze the pattern present in it. In a dataset, it explores each variable separately. It is possible for two kinds of variables- Categorical and Numerical.

@11:06, looks like there is a change in the API, we need to do
sns.countplot(df, x="Survived")

simple and clear teaching, friendly tone. This is a very hard receipr to master and only possible when a guy has done real hard work and does not take himself/herself seriously. You have our respect.

The lecture sets are truly beneficial. Great work. Just a little thing I wanted to point out at 20:33. The y-axis of pdf plots represents the 'density of probability' rather than the density. Integral of the pdf over a range gives the actual probability.

At 20:33 y-axix values are not probability, its probability density
