Design a single-factor experiment, carry it out, and analyse the results. You may choose any area of application, such as a business or industrial process, an academic interest, a sporting activity, or everyday life. Make sure that you have the authority to set the factor levels and that you have a suitable instrument for measuring the response. Your report must consist of the following sections.
(a) State the purpose of your experiment and explain why randomisation was necessary in your experiment.
(b) Write a model for the response in your experiment and carefully explain what each term in the model represents.
(c) Display the data and the ANOVA table.
(d) Express the experimental findings in simple language.
