• Keep the decimal points of the data recorded constant.
• Measurements and readings will be taken carefully in order to minimise human error.
• Use suitable and.appropriate statistical methods to calculate and manipulate the data. (e.g. Graph plotting / calculation of mean, median and mode of the data)
• Ensure that the environment in which the experiment set-ups are located in are exactly the same, if not similar. This is to prevent outside factors from interfering with the results of the experiment.
• Repeat the experiment several times if time permits in order to determine if the data collected from the first experiment was not a one-off happening that would not repeat itself again under the same circumstances.
• Determine the controlled, dependent and independent variables to fully understand how the data should be collected and recorded in such a way that it is clear.
