Correlation ratio

Correlation ratio is a measure of how well two sets of data are related or connected to each other. Imagine you have two groups of toys - a group of superhero action figures and a group of animal toys. If all of the superhero action figures are somehow related to each other and all of the animal toys are related to each other, then the correlation ratio between the two groups would be very low. However, if you have some superhero action figures that have animal sidekicks or some animal toys that have superhero costumes or logos, then the correlation ratio between the two groups would be higher. In other words, the more similarities or connections there are between two sets of data, the higher their correlation ratio will be. The correlation ratio can be calculated using mathematical formulas and can help us understand and predict the relationships between different sets of data.
