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 while there is no linear correlation, there may be a relationship that is not linear. O B. No, because if r= 0, the variables are in a perfect linear relationship. OC. No, because r does not measure the strength of the relationship, only its direction. O D. Yes, because if r= 0, the variables are completely unrelated.

Average

In mathematics, everyone must have heard the term average in one place or other. Almost all types of calculation require taking out an average. In everyday life, the term is used for denoting a certain amount that can be said to be a typical quantity for multiple people or objects. In other words, if a group of people possesses a certain object, then the average gives us an idea regarding the quantity of the object possessed by each person. However, this is solely based on mathematical calculation. It is important to note that most people will not strictly have the average value in a group.
