Question

Find the coefficient of variation (CV) for each sample and answer the following question.

Listed below are systolic blood pressure readings (in mmHg) from samples of adult males and females. Does there appear to be a difference in variation between the two groups?

Male Systolic Blood Pressure (mmHg): $120 comma 125 comma 130 comma 135 comma 128$

Female Systolic Blood Pressure (mmHg): $110 comma 115 comma 118 comma 122 comma 117$

Accepted Answer

Male systolic blood pressure has a slightly higher relative variation than female systolic blood pressure.

Answer

Female systolic blood pressure has significantly higher variation compared to male systolic blood pressure.

Answer

Both male and female groups have the same level of variation in systolic blood pressure.

Answer

The coefficient of variation suggests that male and female systolic blood pressures are not comparable.
