"The slope of the linear regression line can be calculated using any two points in the data.""If the correlation coefficient for a set of data is 0, then the line of best fit is horizontal.""The sum of the residuals for the line of best fit is 0.""If the correlation coefficient is very large, then there must be an outlier in the data.""A negative correlation coefficient means that the data points are very random and don't really fit in a linear model.""A negative residual means that the regression line is very far from the actual data point.""If the correlation coefficient is positive, then the slope of the line of best fit will probably be positive.""If there is a perfect correlation between variables in the data, then the correlation coefficient is 1.""The larger the residual for a given point, the further away the point is from the line of best fit.""If there is a perfect correlation between two variable a and b, then either a caused b or b caused a."
