r = -.23 between the number of interfering mothers-in-law and the number of happy marriages.

How do I interpret the way the variables "go together?"

The coefficient of correlation is denoted by the term 'r' here. It can range from -1 to +1. As the value gets closer to zero, the less is the relationship between variables. When r is positive, it means that the variables have a positive relationship (as one increases, the other one also increases) and when r is negative, it means that they have an inverse relationship (as one increases, the other one decreases). Here, the value is negative. That is, as the number of interfering mother in laws increases, the number of happy marriages decreases. But this relationship is not strong since the value is only -.23, which is near to zero.

These are called compositions of a number n and it is easy to calculate from our understanding of binomial coefficients. So the number of compositions of 4 into 3 parts will be 1+1+2, 1+2+1, and 2+1+1. Note how we think of 1+1+2 and 1+2+1 as different-because in the first case, the first number is 1, second is 1 and third is 2, while...
