Question

Twenty different statistics students are randomly selected. For each of​ them, their body temperature ​(degrees​C) is measured and their head circumference​ (cm) is measured. If it is found that requals​0, does that indicate that there is no association between these two​ variables?

Answer 1

Yes.

Step-by-step explanation:

r is a measurement of value of the linear correlation coefficient which represents all sample data as paired. If the value of r is estimated to be 0, this means that between body temperature (degrees C) and a head circumference (cm) exist no correlation. In statistics, dependence or correlation can be any relationship between two variables, even if it is not causal. It can be any statistical association.
