Question

Quizplus · Accepted Answer

The fact that babies play longer with green fuzzy toys and not with other types of toys suggests that there is an interaction between color and fuzziness. They do not show a preference for either color or fuzziness alone, but rather a combination of the two. Therefore, there is no main effect of color or fuzziness, and fuzziness is not a confounding variable as it is relevant to the question being asked.
