Problem:
The data obtained from the preliminary experiment was incorporated into the main dataset, as the same experimental method, equipment, and controlled conditions were used throughout. This means that the data is directly comparable and valid for inclusion. No significant methodological changes were made that would affect the outcome, ensuring consistency between preliminary and main results. Including the preliminary data increased the overall sample size, which enhances the reliability of the results by reducing the influence of random error and anomalies. It also improved the robustness of the dataset, allowing for a clearer and more representative trend to be identified when analyzing the relationship between pH and mass loss. However, it is important to acknowledge that preliminary data is typically used to refine methods rather than contribute to final results. Despite this, due to the consistency in procedure and conditions, its inclusion is justified and strengthens the overall validity of the investigation. put these in simple English in a paragraph.
