Question

A researcher finds that people who own more than two cars have bigger homes, more garage space, and make more money than people who own only one or two cars. The researcher's inference that having more than two cars causes people to have homes with bigger garages is lacking which type of causal evidence?

Answer 1

Spurious relationship

Step-by-step explanation:

A spurious relationship or spurious correlation[1][2] is a mathematical relationship in which two or more events or variables are associated but not causally related, due to either coincidence or the presence of a certain third, unseen factor.

This is correlation which is produced by an extraneous third factor, and neither of the variables involved in the correlation has influenced the other.A positive correlation between the number of caars obtained and the size of homes is expected. The reason for the correlation is the number of the cars. Bigger homes and more garage space are needed to accomodate more cars, that does not mean they make more money than people who own only one or two cars.
