What is correlation and how do you infer relationship using correlation.

Question

Accepted Answer

Correlation is a statistical measure that shows the relationship between two variables.

Correlation ranges from -1 to 1, where -1 indicates a negative correlation, 0 indicates no correlation, and 1 indicates a positive correlation.
Correlation does not imply causation.
Correlation can be calculated using various methods such as Pearson correlation coefficient, Spearman's rank correlation coefficient, and Kendall's tau correlation coefficient.
Infer relationship using correlation by analyzing the strength and direction of the correlation coefficient.
For example, if the correlation coefficient between height and weight is 0.8, it indicates a strong positive correlation, meaning that as height increases, weight also increases.
However, correlation alone cannot determine the nature of the relationship between two variables and other factors should also be considered.
