The experiment consisted of numerous limitations and uncontrolled variables which impacted on the validity of the outcome.
The lack of repetition was a major limitation in this experiment. The shortage of repetition forbids the elimination of outliers that may cause inaccuracy in the practical outcome. The lack of repetition in this experiment provided erroneous practical results where experimenters are mislead due to outliers, hence conclusions could not be accurately drawn. According to Table 3, Group Three was a clear outlier when it was the only group which provided a negative result for starch concentration inside the dialysis bag. The existence of an outlier impacts on the credibility of the conclusion made by the experimenters. Hence,
