The student clearly described how the data was obtained and processed, ensuring that each procedural step was easy to understand. The recording and processing of data were detailed and precise, with appropriate annotations and correct application of units, decimal places, and significant figures throughout. However, the document lacked a thorough discussion on the impact of uncertainties on the data and results, which was necessary for a complete understanding of the reliability of the findings. Despite this, the work's conclusions remained valid, supported by a strong correlation between temperature treatment and Fe²⁺ concentration. The relevant data processing effectively addressed the research question and demonstrated a systematic approach to data analysis.
