Correlations
Definition
Correlations refer to the statistical relationship between two or more variables. It measures how closely these variables are related to each other, ranging from -1 (perfect negative correlation) to 1 (perfect positive correlation).
Analogy
Think of correlations like a dance partner. If you and your partner move in sync with each other, it indicates a strong positive correlation. On the other hand, if you and your partner move in opposite directions, it represents a strong negative correlation.
