The video above is from a past semester. The material is the same but any dates mentioned will be incorrect. For the current term, please refer to the due dates in syllabus.

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.

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. The correlation coefficient is used to measure the strength of the relationship between two variables. This means that any value beyond this range will be the result of an error in correlation measurement.
