Consider the following argument: A study observed that technology companies offering complimentary daily lunches to employees reported 20% higher project completion rates than technology companies without free lunch programs. The researcher concluded that providing complimentary lunches directly causes an increase in employee productivity. In this argument, the possibility that overall company funding is a third factor influencing both the ability to offer perks and the ability to hire top-performing talent acts as a confounding variable.
Answer: Answer
Answer
The statement is True. Overall company funding represents a classic third-variable confounder that accounts for both the perk (complimentary lunches) and the outcome (higher productivity), undermining the claim of a direct causal relationship.
The claim is accurate because a confounding variable is a third factor that systematically correlates with both the presumed cause and effect. In this scenario, well-funded firms have the budget for employee perks like free lunch and also have the capital to hire more effective teams or build better infrastructure, which explains the higher completion rates without requiring free lunch to be the direct cause.
