Webb7 maj 2024 · To analyze this relationship, he collects data on square footage and house price for 200 houses in a particular city. In this scenario, the real estate agent should use a simple linear regression model to analyze the relationship between these two variables because the predictor variable (square footage) is continuous. Webb28 nov. 2024 · Simple linear regression is a statistical method you can use to understand the relationship between two variables, x and y. One variable, x, is known as the predictor variable. The other variable, y, is known as the response variable. For example, suppose we have the following dataset with the weight and height of seven individuals:
