As this methodology took place in a school environment, it can be expected that during the day of the experiment, 1 or more students may be absent due to various reasons. Although this method is versatile and can be performed in different environments, students participating in varying environments raises the likeliness of varying sound conditions, distractions and overall concentration to a great degree. To improve this, a simple change can be to increase the sample size. Increasing sample size allows for more individuals to partake in this experiment, which provides more data, meaning missing students won't impact the data to a vast degree.
