Continuing from the previous question (Question 4) Jennifer now has a new probleme in addition to when to conduct her experiments. her attempt to expedite her process introduces another variable. In order for her to conduct her experiments at a faster pace, she needs to use two different mixing bowls, a glass one and a wooden one. She cannot measure the effects of this variable., so she is going to use blocking to remove any confounding effects the different bowls might have. In other words she has considered this variable a nuisance variable. Select one of the following options: which is the best choice to confound the mixing bowl variable, using blocking?

Transcribed Image Text:5. Continuing from the previous question (Question 4) Jennifer now has a new problem: in addition to when to
conduct her exxperiments, her attempt to expedite her process introduces another variable.
In order for her to conduct her experiments at a faster pace, she needs to use two different mixing bowls, a gjass
one and a wooden one. She cannot measure the effects of this variable, so she is going to use blocking to remove
any confounding effects the different bowls might have. In other words she has considered this variable a nuisance
variable.
Select one of the following options: which is the best choice to confound the mixing bowl variable, using blocking?
She should confound the mixing bowl variable with factor D. because she expects D won't be an important
variable in the experiment.
