(Type an integer or decimal rounded to one decimal place as needed.) The coefficient of variation for the diastolic measurements is %. (Type an integer or decimal rounded to one decimal place as needed.) Compare the variation. The coefficients of variation for each data set are Therefore, the systolic measurements vary V the diastolic measurements.
