Statistics
Twenty different statistics students are randomly selected. For each of them, their body temperature (°C) is measured and their head circumference (cm) is measured. If it is found that r= 0, does that indicate that there is no association between these two variables? Choose the correct answer below. O A. No, because if r= 0, the variables are in a perfect linear relationship. B. Yes, because if r= 0, the variables are completely unrelated. C. No, because r does not measure the strength of the relationship, only its direction. D. No, because while there is no linear correlation, there may be a relationship that is not linear.
