Numerical Measures - Covariance and Correlation

Описание к видео Numerical Measures - Covariance and Correlation

This video explains the concepts of covariance and correlation, along with how to calculate them with sample data. These are powerful and useful measures of the association of two variables. I cover:

sample covariance as a concept
the formula for sample covariance
an example using temperatures
sample correlation and its comparable features
the formula for sample correlation
population covariance and correlation
