  Indicate whether the statement is true or false


Which of the following is true about correlation statistics?
 
  a. For two variables to be correlated, there can be no exceptions to the pattern in which increases in one variable is accompanied by increases in the other variable.
  b. Two variables can be correlated if increases in one variable are accompanied by decreases in the other variable with most cases, but not necessarily with all cases.
  c. Two variables cannot be correlated if one decreases while the other increases.
  d. When both variables are at the ratio level of measurement, a nonparametric correlation coefficient must be used.


The partial correlation coefficient shows the portion of correlation between two variables that is not shared with other variables.
