A newspaper headline stated that at a recent budget workshop, nearly three dozen people supported a sales tax increase to help deal with the city’s financial deficit (San Luis Obispo Tribune, January 22, 2005).

This conclusion was based on data from a survey acknowledged to be unscientific, in which 34 out of the 43 people who chose to attend the budget workshop recommended raising the sales tax. Briefly discuss why the survey was described as “unscientific” and how this might limit the conclusions that can be drawn from the survey data.
