The student clearly states the independent and dependent variables in the research question, specifying the values of the independent variable and its unit. The method of analysis conducted is described, and the background theory section includes relevant concepts and a diagram. However, the explanation of the choice of techniques for measuring the variables needs to be justified. The document provides a clear explanation of the sampling technique and a discussion on the precision of measurements. The student names and explains controlled variables, addresses safety, ethical, and environmental issues, and describes the methodology sufficiently, ensuring it can be reproduced. There is no irrelevant or repetitive information in the description of the methodology, allowing for an instant understanding.
