What is a non spurious relationship?
Non-spurious relationship — The relationship between X and Y cannot occur by chance alone. Eliminate alternate causes — There are no other intervening or unaccounted for variable that is responsible for the relationship between X and Y.
What is the meaning of spurious relationships?
In statistics, a spurious relationship or spurious correlation 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 (referred to as a “common response variable”, “confounding factor”.

What causes spurious correlations?
A spurious correlation occurs when two variables are statistically related but not directly causally related. These two variables falsely appear to be related to each other, normally due to an unseen, third factor.
What is linear and non linear relationship?
A straight line graph shows a linear relationship, where one variable changes by consistent amounts as you increase the other variable. A curve graph shows a nonlinear relationship, where one variable changes by inconsistent amounts as you increase the other variable.
