Correlation and Regression
Correlation
Regression
This topic looks at correlation and regression. I define a scatterplot and show how to create them. I then discuss how to interpret correlation of a scatterplot. I define the line of regression and show how to use this line to make predictions using the model. I show how to create scatterplots, find the correlation coefficient, and find the regression line in RStudio.
