1. What is correlation?
Correlation is a statistical measure that describes the relationship between two variables. It shows how closely the variables are related to each other and in which direction (positive or negative).
2. What is the range of values that correlation can take?
The range of correlation values is between -1 and 1. A correlation of 1 indicates a perfect positive relationship, -1 indicates a perfect negative relationship, and 0 indicates no relationship between the variables.
3. How can correlation be used in data analysis?
Correlation can be used to determine if there is a relationship between two variables and to what extent they are related. It can help in identifying patterns, making predictions, and understanding the underlying structure of the data.
4. Can correlation imply causation?
No, correlation does not imply causation. Just because two variables are correlated does not mean that one causes the other. There may be other factors at play that are influencing the relationship between the variables.
