Although those involved in the research study sprayed the same amount of sprays for each plant each day, sometimes the bottles would spray a bigger amount than others. Inevitably, that action could cause one impatiens plant to have more herbicide applied to it than another which would cause manipulated results. This could be fixed by pouring the liquid contained in the spray bottle into a measuring device in order to get an exactly equal amount of herbicide applied to both impatiens. Another possible source of error comes from not having separate plastic trays for each impatien plant type, whether it controls, Weed-B- Gone, or Total Kill. In having one tray for all the impatiens could lead to contamination of the sprays to plants that were not assigned to that spray. By the end of day three, there was herbicide liquid residing in the plastic tray which could also cause manipulation. One way to change this experiment in order to make it more valid would be to have more plants to test. The more plants the more data that the researchers replicating this experiment would receive, which would cause their findings to become more structured and
