Understanding Linear Regression
Linear regression is a statistical method used to model the relationship between a dependent variable and one or more independent variables. In simple linear regression, we find the best-fitting straight line for a set of data points. This line is defined by an equation of the form \( y = mx + b \), where \( m \) is the slope and \( b \) is the y-intercept. The slope represents the rate of change of the dependent variable with respect to the independent variable, and the y-intercept is the value of the dependent variable when the independent variable is zero. This tool helps you calculate these values and visualize the line of best fit for your data.
