    so that suggests we have a positive correlation (one variable goes up, the other goes up as well)

    so you need to find one where as one variable goes up, the other goes down

    for instance The distance you live from school and the amount of time it takes to get to school is a positive correlation because as the distance goes up, the time goes up as well

    temp goes up ----> # of people wearing coats goes down
