The student had clearly stated the independent variable, the concentration of indoleacetic acid (IAA), and the dependent variable, the growth of Triticum aestivum seedlings. However, the posed research question had lacked a proper question mark and had not sufficiently described the method of analysis. The background theory section had been incomplete, needing more detail about Triticum aestivum to establish relevance. While the student had effectively explained the choice of techniques and sampling methods, they had not adequately discussed their choices regarding the number of trials and measurement precision. The methodology had generally been clear, but it had lacked detailed instructions for preparing the IAA concentrations, which could have hindered reproducibility.
