o The slope coefficient (identified by the response variable; in this case “Depth”) and the intercept coefficient . These respectively correspond to the slope (m) and the y intercept (b) of your best fit line, and you can plug them into y = m x + b to get the equation of that line.

Correlation Measures of correlation between variables are important to fund managers who are interested in reducing their risk exposure through diversifying their portfolio. Correlation is a measure of the degree to which a value of one variable is related to the value of another. The correlation coefficient is a single number that compares the

ρ is called the Product Moment Correlation Coefficient or simply the Correlation Coefficient. It is a number that summarizes the direction and closeness of linear relations between two variables. The sample value is called r, and the population value is called ρ (rho). The correlation coefficient can take values between -1 through 0 to +1.
