Factors Affecting Student Study Allison FoyJustin Messina

Introduction Students have differing methods of study Assumption: focus and speed (time to complete test) are interrelated

Objective To test if outside factors affect student scores on a basic arithmetic test

Design Three Factors, Factorial ◦ Subjects (Blocking factor) ◦ Music genre (Heavy metal, Classical, No music) ◦ Room temperature (55°F, 70°F) One Replicate 4 x 3 x 2 x 1 = 24 experiments

Analysis of Variance on Score Subject Music150.58

Analysis Observations: Subject = significant Music = significant Temperature = not significant *Subject appears to more heavily affect results

Analysis of Variance with Interaction

Analysis Observations: Initially, no error or F-values; significance estimation based on Seq SS values ◦ Subject = significant ◦ Music = significant ◦ Temperature = not significant *All 2-way and 3-way interactions were determined to be not significant

Conclusions Subjects have different skill levels Heavy metal music produces the lowest scores No music and classical music produce the highest scores Room temperature does not affect score
