Define no correlation. Choose the correct answer below. A. No correlation means that there is no apparent relationship between the two variables. An example might be hair color and weight. B. No correlation means that both variables tend to increase (or decrease) together. An example might be shoe size and height. C. No correlation means that two variables tend to change in opposite directions, with one increasing while the other decreases. An example might be age and vision. D. No correlation means that the two variables are always zero. Only trivial examples exist for this type of correlation.

A. No correlation means that there is no apparent relationship between the two variables. An example might be hair color and weight. Picture a world where people with blonde hair don't weigh any more or less than those with brown or black hair—just like trying to predict one variable based on the other, it's simply a shot in the dark! In real life, no correlation pops up more often than you think! For instance, the relationship between the number of hours spent watching TV and your shoe size typically reveals no connection at all. So, while your binge-watching marathon is great for relaxation, it won't magically make your feet grow bigger!
