Simple Linear Regression in R for Dummies What is it? Simply put, simple linear regression is a method that helps us model the relationship between two variables. When we have multiple variables, we have multiple linear regression. This concept is an important concept used in data analysis, and can tell us a lot about a dataset. When working with data with two variables, an independent and dependent variable, we sometimes wish to see the relationship those two. We want to see if the influence of one variable (independent) has an impact on the value of another variable (dependent). i In Practice One way to see this relationship is by plotting the data in a scatter plot, and then finding the line of best fit, which is essentially a line with form y = mx+b that best fits the data points in the scatter plot. There is quiet a lot of math behind finding these values m and b, but R makes this process very simple. Take the following data set for example: Link for dataset: htt...
