Question

a published study found a correlation between holidays celebrated and homework assignments. is causation likely or unlikely?

• causation is likely. it is reasonable to say teachers assign more homework on holidays.
• causation is unlikely. a third variable could be school vacations increase both homework assignments and holidays celebrated.
• causation is likely. a third variable could be school vacations increase both homework assignments and holidays celebrated.
• causation is unlikely. it is reasonable to say teachers assign more homework on holidays.

Analyze the relationship

The study describes a correlation between holidays celebrated and homework assignments. We must determine if celebrating holidays directly causes more homework, or if another factor is at play.

Evaluate causation likelihood

Using our understanding of Independent and Dependent Variables, celebrating a holiday does not directly force a teacher to assign homework. Therefore, a direct causal link is highly unlikely.

Identify confounding variables

A third variable, such as school vacations (e.g., winter or spring break), often leads to both more celebrated holidays and teachers assigning holiday homework packages. This explains the observed correlation without direct causation.

Select the correct option

The second option correctly states that causation is unlikely and identifies school vacations as a plausible third variable driving both factors.
