What is regression analysis with example?

Regression analysis is a statistical technique used to analyze the relationship between variables. For example, we can use it to study the connection between hours studied and exam scores. By collecting data from students, we can determine if there is a positive correlation between the two variables. Regression analysis provides a regression equation that helps predict exam scores based on the number of hours studied. This analysis allows us to quantify the relationship, identify patterns, and make predictions based on observed data. It is widely used in various fields such as economics, social sciences, finance, and marketing.
