Korelacijo

Korelacijo is a term used in statistical analysis to describe the relationship or association between two or more variables. It quantifies the degree to which variables change together. A positive correlation indicates that as one variable increases, the other tends to increase as well. Conversely, a negative correlation means that as one variable increases, the other tends to decrease. The strength of the correlation is measured on a scale from -1 to +1. A correlation of +1 signifies a perfect positive linear relationship, while a correlation of -1 indicates a perfect negative linear relationship. A correlation of 0 suggests no linear relationship between the variables. It is crucial to remember that correlation does not imply causation. Just because two variables are correlated does not mean that one causes the other; there might be an underlying third variable influencing both. Commonly used measures of correlation include Pearson's r for linear relationships and Spearman's rho for monotonic relationships. Understanding korelacijo is fundamental in various fields, including economics, psychology, and natural sciences, for identifying trends, making predictions, and exploring potential causal links.
