Ice cream and Drowning

I had a seventh grade teacher who posed the question “Every year when ice cream consumption increases the number of drowning accidents increases. Why is that?”

We all thought hard about how the two could be related but couldn’t come up with an answer. Finally the teacher said “As the weather gets warmer more people eat ice cream and more people go swimming. If more people go swimming then more drowning accidents will occur. But ice cream consumption and drowning are unrelated.”

Don’t confuse correlation with causation.
