One variable is considered to be an explanatory variable, and the other is a. Here’s how it works: Understanding Simple Linear Regression: It’s a way to model the relationship between two variables by fitting a linear equation to observed data. Simple linear regression is a way to describe a relationship between two variables through an equation of a straight line, called line of best fit, that most closely models this relationship. In statistics, linear regression is a statistical model which estimates the linear relationship between a scalar response and one or more explanatory variables (also known as dependent and independent variables ). Linear regression isn’t as complex as it sounds. You can now enter an x-value in the box below the plot, to calculate the predicted value of y.Above the scatter plot, the variables that were used to compute the equation are displayed, along with the equation itself. On the same plot you will see the graphic representation of the linear regression equation. If the calculations were successful, a scatter plot representing the data will be displayed.To clear the graph and enter a new data set, press "Reset".Press the "Submit Data" button to perform the computation.This flexibility in the input format should make it easier to paste data taken from other applications or from text books. Individual values within a line may be separated by commas, tabs or spaces. Individual x, y values on separate lines. X values in the first line and y values in the second line, or. x is the independent variable and y is the dependent variable. Enter the bivariate x, y data in the text box. This page allows you to compute the equation for the line of best fit from a set of bivariate data:
