Covariance is a statistical measure that indicates the relationship between two variables.
2. How to calculate covariance ?
Covariance can be calculated using the formula: \[ cov(X,Y) = \frac{\sum_{i=1}^{n}(X_i - \bar{X})(Y_i - \bar{Y} )}{n} \]
3. What is the difference between positive and negative covariance ?
Positive covariance indicates that variables tend to move in the same direction, while negative covariance indicates that they tend to move in opposite directions.
4. What are limitations of the covariance calculator ?
Limitations include sensitivity to extreme values in the data and the inability to capture non-linear relationships.
5. Where can I find online tools to calculate covariance ?
Some options include CalculatorSoup, Desmos, and Wolfram Alpha.
