Or you can say it the other way round  That'll be a negative correlation  Now the alternative would be when you plot them you get a circle almost, you get, there appears to be no systematic relationship between the two  So what you'd be tempted to say is, no correlation  Now I'm gonna try and move towards how we might measure, how might we actually measure, get a measure of correlation because what you'd be able to say is, well they're more correlated or less correlated.
