The Linear Regression Equation. Linear regression is a way to model the relationship between two variables. You might also recognize the equation as the slope formula.The equation has the form Y= a + bX, where Y is the dependent variable (that’s the variable that goes on the Y axis), X is the independent variable (i.e. it is plotted on the X axis), b is the …Sep 20, 2016 · How to use a TI-84 calculator to make a LSRL (Least squares regression line) First, let’s find a regression line to fit the data. Then we’ll graph the scatterplot of the data, along with the regression line. Lastly, we will use the model to predict the test score grade of a student that studies 11 hours. To fit a linear function to the data using regression, let’s select the EDIT option of the STAT menu.

When you make the SSE a minimum, you have determined the points that are on the line of best fit. It turns out that the line of best fit has the equation: ^y =a+bx y ^ = a + b x. where. a =¯¯y −b¯¯x a = y ¯ − b x ¯. and.

The TI-83 can be used to fit various empirical models: linear (using least squares or median-median regression), polynomial (quadratic, cubic, and quartic), exponential, logarithmic, power, logistic, and sinusoidal. In what follows we fit linear and polynomial models to data and plot the results. ∑ Enter the Data 8) Press [Right Arrow] until you select 'b and press [tab]. 9) Press [enter].
