Analysis with correlation and regression

Correlation and regression analysis are statistical methods used to study the relationship between two or more variables.

Correlation is a measure of the strength and direction of a linear relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative correlation, 1 indicates a perfect positive correlation, and 0 indicates no correlation.

Regression, on the other hand, is a statistical method used to model the relationship between a dependent variable and one or more independent variables. The goal of regression analysis is to find the line of best fit (also known as the regression line) that describes the relationship between the dependent and independent variables.

Both correlation and regression are commonly used in fields such as economics, finance, and psychology to analyze data and make predictions.
