Example: Survey Sampling and Analysis Procedures

This section demonstrates how you can use the survey procedures to select a probability-based sample and then analyze the survey data to make inferences about the population. The analyses include descriptive statistics and regression analysis. This example is a survey of income and expenditures for a group of households in North Carolina and South Carolina. The goals of the survey are as follows:

  • Estimate total income and total living expenses

  • Estimate the median income and the median living expenses

  • Investigate the linear relationship between income and living expenses
