The student clearly described how the data were obtained and processed, making each procedural step easy to understand, particularly through detailed explanations of pH and absorbance measurements. The data recording and processing were presented in detailed tables and graphs, appropriately annotated with correct units and significant figures. However, the student did not adequately address the impact of uncertainties on the data and results, thereby reducing the reliability and interpretability of their findings. Despite this, the work maintained validity in its conclusions, supported by quantitative data that demonstrated a clear relationship between the volume of orange peel solution and both pH and absorbance. Overall, the student conducted relevant data processing that effectively addressed the research question.
