Specifically, she will examine whether participants spend more time at the digital animal exhibit or the real animal exhibit.

(1) Define the term “research confound.” Does Dr. Bright have any research confounds in her study (and if so, list them)?    (2) Is Dr. Bright’s conclusion that 8-year-olds prefer digital exhibits valid? Explain with reference to the appropriate…
