In Chapter 3, we looked at numerically summarizing data from one variable univariate data , but newspaper articles and studies frequently describe the relationship between two variables bivariate data. It's this second class that we'll be focusing on in Chapter 4. There are plenty of variables which seem to be related. The links below are articles from various news sources, all discussing relationships between two variables. Proximity to highways affects newborns' health: study.

Published on May 13, by Shaun Turney. Revised on February 10, The Pearson correlation coefficient r is the most common way of measuring a linear correlation. It is a number between —1 and 1 that measures the strength and direction of the relationship between two variables. The longer the baby, the heavier their weight. The price of a car is not related to the width of its windshield wipers. Between 0 and —1 Negative correlation When one variable changes, the other variable changes in the opposite direction. The higher the elevation, the lower the air pressure.

The word "correlation" is made by clubbing the words "co" and "relation". The word "co" means together, thus, correlation means the relationship between any set of data when considered together. For electricity generation using a windmill, if the speed of the wind turbine increases, the generation output will increase accordingly. Thus, the variable speed and electricity output have a positive correlation here. In this mini-lesson, we will study the correlation coefficient definition and the correlation coefficient formula. Check out the interactive examples on correlation coefficient formula, along with practice questions at the end of the page.
