I am having trouble identifying the confounding variable.

Is the confounding variable the excitement of being with other kids at the party?

"In statistics, a confounder (also confounding variable, confounding factor or lurking variable) is a variable that influences both the dependent variable and independent variable causing a spurious association. Confounding is a causal concept, and as such, cannot be described in terms of correlations or associations."
