You are interested in determining the distribution of income in a county (central tendency, as well as variability). Costs prohibit a complete census. You must determine a sampling methodology for the study. The population is diverse, with a significant homeless population, both English and non-English speakers, and a broad spectrum of incomes, including a small, but very wealthy gated community. Identify the ethical issues involved:

Choices:

The analysis and reporting should consider the impact of extreme values in the data.

Consider both the impact of extreme values and methods of including homeless and non-English speakers.

There are none. It’s a simple mathematical operation.

In order to get a random and representative sample, methods of including homeless and non-English speakers need to be considered.
