MOM'S SECRET ROOM

[ONEBGG]

Once upon a time, a psychologist conducted a survey and gathered considerable amounts of data. However, as is the case many times, the data sat on the shelf gathering dust. But, one year, the psychologist decided to resurrect the data. Not being exactly sure of what to do though, the data was given to a few students to play with and summarize.
Well, as you might expect, one student did it one way, another student did it another way, and a third student even did it entirely different from the other two. Because of this, the psychologist suddenly became interested in a different question and .. proclaimed to the world:

"How goes this VARIANCE OF ANALYSIS?"
