Ms. Li, a principal, is interested in the differences in student behavior between two of the third-grade classrooms at her school. She asks the teachers, Mr. Williams, whose class meets at 9:00, and Ms. Walsh, whose class meets at 1:00, to record over a week the number of times students in their classrooms act out. Mr. Williams’ class has 31 students, and Ms. Walsh’s class has 32 students. "Acting out" is defined as students speaking without raising their hand or getting out of their seats without being given permission. At the end of the week, Mr. Williams reports that on average, his students acted out 73 times a day, and Ms. Walsh reports that, on average, her students acted out 27 times a day. Ms. Li decides that the students in Ms. Walsh's classroom act out more often than those in Mr. William's class. The results of this study are inconclusive because

Since the classes are held at different times of the day, the study will not be conclusive. The study needs to be held during the same times so that the principal can see how both classes act. Many times students get more restless after lunch and near the end of school. While students are not as restless in the morning time since school hasn't been in session as long. She can redo the study using the same classes but at the same time frame.

The results of this study are inconclusive because the confounding variable in this situation is the time of the day and the classes are not held on same day.

The fact that the classes aren't held on the same time in the day but rather, on different times, will lead to the inconclusiveness of the study.

The study needs to be held at the same time in order for the principal to see how both of the classes act.

In conclusion, it will be difficult for the principal to determine the differences in the behavior of the students between the two of the third-grade classrooms at her school.
