The student clearly states the independent and dependent variables in the research question, identifying the tension in an electric guitar string and the fundamental frequency measured in hertz. The method of analysis is well described, specifying the use of a digital tuner to measure the frequency as tension increases. The background theory is comprehensive, explaining the relationship between tension and frequency and including relevant physics principles. The choice of techniques for measuring the variables is clearly explained, and the student discusses their sampling technique, emphasizing the importance of controlled variables and safety considerations. However, the methodology lacks sufficient detail for reproducibility, specifically regarding the pendulum mechanism used, which could be improved for clarity.
