Using Portfolio Theory to Value Power Generation Investments Correlation, diversity and risk The correlation coefficient, ρ, is a measure of diversity. Lower ρ among portfolio components creates greater diversity, which reduces portfolio risk σp. More generally, portfolio risk falls with increasing di...
In the example, you'd enter "=TDIST(C3, 18, 2)" to find the P-value. Generally, a result is considered significant if P < 0.05. Other Versions of Excel With newer versions of Excel, the process for finding the correlation coefficient and performing a significance test in Excel is exact...

There are many interpretations that can be made from the correlation coefficient. The sign of the Pearson correlation denotes the direction of the relationship (e.g., positive or negative), and the value of the Pearson denotes the strength of the relationship. The Pearson ranges within a scale...
