A scatter plot of the two variables will be created. Because we contrived the dataset, we know there is a relationship between the two variables. This is clear when we review the generated scatter plot where we
A computer while calculating the correlation coefficient between the variables x and y obtained the following results : n=25,∑xi=125,∑yi=100,∑x2i=650,∑y2i=460,∑xiyi=508It was however later discovered at the time of checking that it has copied down two pairs of obervations as (6...

The formula for correlation is equal to Covariance of return of asset 1 and Covariance of asset 2 / Standard. Deviation of asset 1 and a Standard Deviation of asset 2. ρxy =Correlation between two variables Cov(rx, ry) =Covariance of return X and Covariance of return of Y ...
Pearson's correlation coefficient is a simple way of calculating the degree of correlation between two variables, returning a value (calledr) ranging from −1 to 1. A perfect correlation (r= 1) between two variables would be where an increase in one variable by a certain amount leads to ...

give positive returns, while negative covariance means returns move in the opposite direction. Covariance is usually measured by analyzing standard deviations from the expected return, or we can obtain it by multiplying the correlation between the two variables by the standard deviation of each ...
Projections.If a company finds a positive correlation between two variables and has some predictions on the one variable involved in the correlation then they can try to make predictions on the second variable as well. For example:Company X finds a positive correlation between the number of touris...
Correlation measures the degree of association between two variables, while causation suggests a causal relationship that may or may not exist. An interesting example of this distinction is the correlation between ice cream sales and shark attacks: while both increase in the summer...
