lima 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 foundthat r = 0, does that indicate that there is no association between these two variables?Choose the correct answer below.O A. No, becauser does not measure the strength of the relationship, only its direction.O B. Yes, because if r = 0, the variables are completely unrelated.O C. No, because if r = 0, the variables are in a perfect linear relationship.O D. No, because while there is no linear correlation, there may be a relationship that not linear.

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.A correlation coefficient denoted by 'r' measures the linear relationship between two variables. When the correlation coefficient 'r' is equal to 0, it means there's no linear relationship between the variables. Correlation coefficient measures the strength of linear relationship but it does not measure the strength of non-linear relationship between two variables.There might be relationship between the two variables that is non-linear. The correlation coefficient of 0 doesn't confirm the absence of any relationship, but specifically, it indicates the absence of a linear relationship between the variables. Therefore, correlation coefficient 'r' = 0, does not imply that there is no relationship between the two variables.The correct answer is option (D), "No, because while there is no linear correlation, there may be a relationship that is not linear".The correct answer is option (D), "No, because while there is no linear correlation, there may be a relationship that is not linear".
