Finding the equation will also give you the slope. A linear regression line equation is written in the form of: Y = a + bX where X is the independent variable and plotted along the x-axis Y is the dependent variable and plotted along the y-axis The slope of the line is b, and a is the intercept (the value of y when x = 0). Some More Examples of Linear Regression Analysis: Suppose we have nine students with their IQ level and the number they scored on Test. Step 1: Press STAT, then press ENTER to enter the lists screen. Linear regression can be used in market research studies and customer survey results analysis. The formula for the y-intercept contains the slope! Simple regression dataset Multiple regression dataset Table of contents Getting started in R Step 1: Load the data into R Step 2: Make sure your data meet the assumptions Step 3: Perform the linear regression analysis Step 4: Check for homoscedasticity Step 5: Visualize the results with a graph Step 6: Report your results Getting started in R She is the author of
