... We now present two numerical measures of linear relationship that provide information as to the strength & direction of a linear relationship between two variables (if one exists). They are the covariance and the coefficient of correlation. Covariance - is there any pattern to the way two variables ...

... 1. We make the most conservative estimate of the sample size n by using p = 0.50. For a given E , this value of p will give us the largest sample size in comparison to any other value of p because the product p ⋅ q = 0.50 ⋅ 0.50 is greater than the product of any other pair of values for p and q. 2. ...
