Tolong jelaskan mengenai Pearson product-moment correlation coefficient dalam bahasa sunda

Dina matematik, sarta dina sabagéan statistik, the Pearson product-moment correlation coefficient (r) is a méasure of how well a linear equation describes the relation between two variables X and Y méasured on the same object or organism. It is defined as the sum of the products of the skor standard of the two méasures divided by the degrees of freedom:

The result obtained is equivalent to dividing the covariance between the two variables by the product of their standard deviations. In general the quantity of a correlation coefficient is the square root of the coefficient of determination (r2), which is the ratio of explained variation to total variation:
