The slope coefficient
WebFeb 7, 2013 · The correlation coefficient r gives you a measurement between − 1 to + 1. This gives you information about the strength of the linear relationship that can be interpreted independently of the scale of the two variables. Again, when s d y = s d x, then m = r. WebThis coefficient represents the mean increase of weight in kilograms for every additional one meter in height. If your height increases by 1 meter, the average weight increases by 106.5 kilograms.

Web9.2.2 - Interpreting the Coefficients. Once we have the estimates for the slope and intercept, we need to interpret them. Recall from the beginning of the Lesson what the slope of a … WebJan 22, 2024 · To test if the slope coefficient is statistically significant, we can calculate the t-test statistic as: t = b 1 / se(b 1) t = 2.7037 / 0.7456; t = 3.626; The p-value that corresponds to this t-test statistic is shown in the column called Pr(> t ) in the output. The p-value turns out to be 0.00464.
