Denise heard that little children pick food based upon color. She read many studies about food color and selection. She learned when foods are not the color people expect, it makes them think the flavor is different. To test this, she offered 100 kindergarten children colored mashed potatoes for lunch. The colors served were red, yellow, green, and blue. As the students selected the mashed potatoes, she wrote down which color each student selected. She then counted how many students selected each color.
There is an experimental design flaw in Denise’s experiment. What part of the experiment does it involve?
A. Independent Variable
B. Dependent Variable
C. Control
D. Replicates

22. How could Denise fix her experimental design flaw?
A. Offer normal, white mashed potatoes
B. Serve 100 more students
C. Serve both mashed potatoes and ice cream
D. Only record the number of students who do not get mashed potatoes

In Denise’s experiment, the absence of the control is the experimental design flaw that can be fixed by offering normal, white mashed potatoes. Thus, options C and A are correct.

What is experimental design?

The experimental design organizes and interprets the outcomes concluded from the experiment trials. An experimental design always must have control along with the variables to compare the data accurately.

In Denise’s experiment, the absence of the control can be fixed by offering normal white mashed potatoes to the kindergarten children so that the data can be compared.

Therefore, the lack of a control group is the flaw of the experimental design.
