![]() For example, if you wanted to generate a line of best fit for the association between height and shoe size, allowing you to predict shoe size on the basis of a person's height, then height would be your independent variable and shoe size your dependent variable). To begin, you need to add paired data into the two text boxes immediately below (either one value per line or as a comma delimited list), with your independent variable in the X Values box and your dependent variable in the Y Values box. This video gives step-by-step instructions on how you input data in a graphing calculator and then look at the calculator produced scatterplot, find the linear regression model (line of. ![]() This calculator will determine the values of b and a for a set of data comprising two variables, and estimate the value of Y for any specified value of X. Graphing linear regression The Linear Regression calculator provides a generic graph of your data and the regression line. Plug in any value of X (within the range of the dataset anyway) to calculate the corresponding prediction for its Y value. The line of best fit is described by the equation ลท = bX + a, where b is the slope of the line and a is the intercept (i.e., the value of Y when X = 0). Finally the equation is given at the end of the results section. This regression equation calculator with steps will provide you with all the calculations. Step 2: Type in the data or you can paste it if you already have in Excel format for example. This simple linear regression calculator uses the least squares method to find the line of best fit for a set of paired data, allowing you to estimate the value of a dependent variable ( Y) from a given independent variable ( X). The steps to conduct a regression analysis are: Step 1: Get the data for the dependent and independent variable in column format.
