Today we’re going to talk about data relationships and what we can learn from them. We’ll focus on correlation, which is a measure of how two variables move together, and we’ll also introduce some useful statistical terms you’ve probably heard of like regression coefficient, correlation coefficient (r), and r^2. But first, we’ll need ...

Understand scatterplots and correlation. Learn about no correlation, positive correlation, and negative correlation scatterplots and how to interpret them.

Negative correlation is a relationship between two variables in which one variable increases as the other decreases, and vice versa.

Correlation is used to understand the relationship between variables. However, correlation does not imply causation.

Whenever the "correlation vs. causation" topic comes along, it's easy to imagine a tongue-in-cheek comment by let's say an economics or philosophy professor, who explains that correlation does not imply causation. And, indeed, the fact that correlation does not imply causation is well known but... well, improperly understood. It's one of those ...

A correlational research design investigates relationships between variables without the researcher controlling or manipulating any of them. A correlation reflects the strength and/or direction of the relationship between two (or more) variables. The direction of a correlation can be either positive or negative. ⭐️SUPPORT THE CHANNEL⭐️ ...

How to calculate Pearson's r correlation coefficient Warning: I calculated the degrees of freedom (df) incorrectly. The N is 7, not 14. I counted the number of scores (which is typical in other calculations), instead of the number of cases. In this example, the df is indeed 5, meaning the critical value is 0.669, which is greater than the ...

In a regression analysis, multicollinearity occurs when two or more predictor variables (independent variables) show a high correlation. This leads to the fact that the regression coefficients are unstable and can no longer be interpreted. To avoid multicollinearity, there must be no linear dependence between the predictors; this is the case ...

Many of those who have the best of intentions with respect to learning what the Pearson correlation coefficient is all about end up giving up quickly because in most cases, the explanations they come across are boring and overly-complicated.
