Medical Wonders is a specialized interior design company focused on healing artwork. The CEO, Kathleen Kelledy, claims that artwork has healing effects for patients staying in a hospital, as measured by reduced length of stay. Her current client is a children’s cancer hospital. Kathleen is interested in determining the effect of three different pieces of healing artwork on children. She chooses three paintings (a horse photo, a bright abstract, and a muted beach scene) and randomly assigns six hospital rooms to each painting. In Kathleen's experimental design, "painting style" is _______.

Explanation:
The treatment variable should be the three types of painting and hence we decide that the painting style should be the treatment variable to examine the data and carry forward to the analysis of variance to examine the effect of six hospital rooms on children.
