Correlation analysis
With the help of correlation analysis, the linear relationship between variables can be examined. The strength of the correlation is determined by the correlation coefficient, which varies from -1 to +1. This means that correlation analyses can be used to make a statement about the strength and direction of the relationship between two variables.
Interpret correlation
Positive correlation
A positive correlation exists when larger values of variable A are accompanied by larger values of variable B. Body size and shoe size, for example, correlate positively, resulting in a correlation coefficient that lies between 0 and 1, i.e. a positive value.
Negative correlation
A negative correlation exists when larger values of variable A are accompanied by smaller values of variable B. The product p...

Introduction to Correlation (Statistics)
This video provides an introduction to correlation, which is used to understand the relationship between variables. (As an example, we could evaluate the relationship between the amount of rain and the number of raincoats that are sold.) Correlation is measured using the correlation coefficient (r).

Pearson's Correlation, Clearly Explained!!!
Correlation is one of the most basic statistical measures of how two different things might be related, which means it is very important to have a clear understanding of what it means and how it works. This StatQuest walks you through everything you need to know about Correlation. It tells you what it means, how to interpret it, and what its limitations are.

Negative correlation
A negative correlation exists when larger values of variable A are accompanied by smaller values of variable B. The product price and the sales volume usually have a negative correlation; the more expensive a product is, the lower the sales volume. In this case, the correlation coefficient lies between -1 and 0, i.e. it takes on a negative value.

What is Correlation?
Correlation is a statistic that measures the degree to which two variables move in relation to each other. It measures association, but doesn't show if x causes y or vice versa—or if the association is caused by a third factor.

Probability and statistics on Khan Academy: We dare you to go through a day in which you never consider or use probability. Did you check the weather forecast? Busted! Did you decide to go through the drive through lane vs walk in? Busted again! We are constantly creating hypotheses, making predictions, testing, and analyzing. Our lives are full of probabilities! Statistics is related to probability because much of the data we use when determining probable outcomes comes from our understanding of statistics. In these tutorials, we will cover a range of topics, some which include: independent events, dependent probability, combinatorics, hypothesis testing, descriptive statistics, random variables, probability distributions, regression, and inferential statistics. So buckle up and hop on for a wild ride. We bet you're going to be challenged AND love it!
About Khan Academy: Khan Academy offers practice exercises, instructional videos, and a personalized learning dashboard that empower learners to study at their own pace in and outside of the classroom. We tackle math, science, computer programming, history, art history, economics, and more. Our math missions guide learners from kindergarten to calculus using state-of-the-art, adaptive technology that identifies strengths and learning gaps. We've also partnered with institutions like NASA, The Museum of Modern Art, The California Academy of Sciences, and MIT to offer specialized content.
For free. For everyone. Forever. #YouCanLearnAnything
