When conducting ANOVA to analyze the concentration of heavy metals in soil, due to the non-normal distribution of the raw data, a Box-Cox transformation was performed to achieve normality. However, it should be noted that the transformed data exhibited significant alterations in terms of mean, median, and overall magnitude compared to the raw data. Therefore, when carrying out subsequent research on heavy metal pollution evaluation (e.g., calculating Igeo geological accumulative index, Kriging difference of concentration spatial distribution, and descriptive statistics), it is crucial to determine whether to utilize pre-transformed or post-transformed data?
