- Julio, a student, conducted a survey to help decide which of two prototype t-shirt designs ("party time" red or "traditional" white) to sell to raise funds to pay off student loans. - The survey sample was a non-probability convenience sample of students, which will be difficult to generalize. Additional questions on purchase intentions and motivation would have been more useful. - The report recommends discussing limitations of the sampling and research design given the objective of raising funds. More research is needed to reduce financial risk, or Julio could order an even number of both shirt designs.
