- A negative correlation between two variables means that they fluctuate in opposite ways (one increases and other decreases)
In this example, the number of hot chocolates <u>increases</u> as temperature outside <u>decreases</u>. The variables that are correlated are the temperature and the number of hot chocolates sold.
