Susan would like to study the effect of background noise on learning. She recruits 24 students from her class and has each student study with a constant background sound, an unpredictable background sound, and then with no sound at all. The order of the background sound conditions was randomly assigned to each student. After studying under all conditions, each student took a 10 point multiple choice test over the material. What can Susan conclude from the study design?

Linear Functions
A linear function can just be a constant, or it can be the constant multiplied with the variable like x or y. If the variables are of the form, x2, x1/2 or y2 it is not linear. The exponent over the variables should always be 1.

What can Susan conclude from the study design?
O Susan can conclude that the 24 students will represent the overall population of all
college students
O Susan can conclude that there will be differences among the study types
O Susan can conclude that individual differences due to learning styles are removed
from the analysis
O Susan can conclude that students will perform best given the background sound
condition that they use most often to study
