Question

What is the most likely value of the correlation coefficient of the data in the table? Based on the correlation coefficient, describe the relationship between time and velocity of the toy car.

Answer 1

A correlation coefficient is a measure of the strength of dependence and correlation of a set of data. It shows how good is the fitted model to the data. It will have values ranging from -1.0 - 1.0. Having a coefficient that is the lower or the upper limit will tell you that the model best fit the data and a good correlation. However, as it goes farther from the limits then the correlation is to be a bad one.
