A lot of people often confuse correlation by saying you that one variable causes another variable. This is an incorrect conclusion, because correlation can be misused in this way. It is possible when you are looking at 2 variables that are so closely related where you may say one causes the other. For example, if you look at the correlation between reading the material in class and your problem set grade, then you might assume a cause and effect relationship. However, if you look at the relationship between eating ice cream in Montana and car accidents in Washington DC, then it's less likely you may say one causes the other.
How may correlation analysis be misused to explain a cause-and-effect relationship?
