+1 Fantastic example, this is exactly the context in which I had encountered Markov Chains. Whish I could vote up more than once.

comment What can we conclude from correlation?
This is wrong: "We can conclude that many people become right-handed as they grow older." We cannot conclude this at all from the given data. For one, the study only takes a sample at one point in time, rather than selecting a sample and monitoring their progress through many decades. This is what would be needed for us to even entertain the possibility that aging causes a change in handedness. There are many other possibilities in my answer and in others which account for the skewed proportions without requiring people to change handedness with age, which is what you falsely concluded.

@Kaestur, you cannot conclude that people become right handed, only that the proportion of right handed people to left handed people appears larger. Sure, left handed people learning to use their right hands is one possibility, but definitely not the only one, and I give two other possibilities in my answer.
