WebJan 10, 2024 · Simple linear regression is an approach for predicting a response using a single feature. It is assumed that the two variables are linearly related. Hence, we try to find a linear function that predicts the response value (y) as accurately as possible as a function of the feature or independent variable (x). WebFor this analysis, we will use the cars dataset that comes with R by default. cars is a standard built-in dataset, that makes it convenient to demonstrate linear regression in a simple and easy to understand fashion. You can access this dataset simply by typing in cars in your R console. You will find that it consists of 50 observations (rows ... WebA scatter diagram is a graph that uses dots to represent values for two different variables. The position of each dot on the horizontal and vertical axis indicates values for an individual data point. For example, a scatter diagram can be used to show the relationship between hours spent studying and exam scores. the piarist
