We only collected data on two variables engagement and satisfaction but how do we know there isnt another variable that explains this relationship? For example, if we want to estimate the effect of education (treatment) on future income (outcome variable), there is a confounding variable called ability that we need to include in the regression. Cholera is caused by the bacterium Vibrio cholerae, originally identied by Filippo Pacini in 1854 but not widely recognized until re-discovered by Robert Koch in 1883. . 2. To isolate the treatment effect, we need to make sure that the treatment group units are chosen randomly among the population. Students who got scholarships are more likely to have better grades even without the scholarship. A causative link exists when one variable in a data set has an immediate impact on another.
