Determining the strength of a correlationis very important to determine how well one variable can predict another. To determine the strength of a correlation, we have to calculate the correlation coefficient, r.
Explain how people’s scores on two variables can be used to calculate r.
Supposing scores of a group of students in two subjects English (x) and Math (y) are given. Using appropriate formulas, we can determine the correlation coefficient, r between x and y.
Here is an example on how this is done:
Score in …
The expert explains how people’s scores on two variables are used to calculate r. A complete, neat and step-by-step solution is provided in the attached file.
