Explanation / Answer

Solution:-

Lurking Variable. A well-designed experiment includes design features that allow researchers to eliminate extraneous variables as an explanation for the observed relationship between the independent variable(s) and the dependent variable.

A lurking variable can falsely identify a strong relationship between variables or it can hide the true relationship. For example, a research scientist studies the effect of diet and exercise on a person's blood pressure. Lurking variables that also affect blood pressure are whether a person smokes and stress levels.

In statistical models, the error term explains lurking variables that affect the process. To discover lurking variables, you must take the time to understand your data and the important variables that can affect a process.

In this question the possible lurking variable is that, the students may not have responded honestly. (B)
