Answer:
spurious relationship
Explanation:
A spurious relationship I statistics is where two variables are related but a third unknown variable has not been considered.
An example is if a shop sells more of air-conditioners when there is high rate of drowning in a town's swimming pool. The relationship between there two is unclear, but when you consider that both occur during the hot season you see that heat causes more swimming and also more sale of air-conditioners.
