﻿ Correlation Coefficient. How to calculate the correlation coefficient

# Correlation Coefficient

Correlation coefficient measures the relationship between two variables.

The three scatter plot graphs below represent example of data with different correlation coefficients. One of the graphs demonstrates a positive correlation coefficient. The other graph has a negative correlation coefficient, and one of the graphs has no correlation between the two variables at all. Can you identify which graph goes with which type of correlation coefficient? ### Examples of positive and negative correlation coefficients

Example of a strong positive correlation Example of the graph with a negative correlation coefficient p>The points below do not have any clear positive or negative correlation. Below is a more realistic example of a negative correlation (Note: the data below is completely made up. I have no idea if playing video games has any correlation to grade point average!) Below is a more realistic example of a positive correlation (Note: the data below is completely made up. I have no idea if the correlation between studying and gpa exists!) ### Ultimate Math Solver (Free)
