A researcher found that there is a positive correlation between living in a house with more than two bathrooms and grades earned. Based on this observation, why is it not possible to conclude that having more bathrooms causes higher grades? What are some alternative explanations for the observed correlation? Be sure to explain your answer.

It is Not possible as grades can be affected by many other psychological factors such as the students motivation and effort as well as the factors in the school which has a direct correlation to a students grades. Having two bathrooms would indicate that one is probably more wealthy and hence has more financial resources to support the child education. However, this does not provide a direct link to a child's grades hence while there can be a possible correlation. It is not necessarily the best Nor most accurate
