Questions to be addressed

The following topics in survey design will be addressed:

• Methods of deriving population estimates and their standard errors.

• The importance of understanding the way that a sampling frame has been planned when estimating population values.

• The importance of ensuring as far as possible random sample selection.

• The value of stratification.

• Possible use of ancillary information in improving precision of population estimates.

We use Microsoft Excel to demonstrate the calculations of population totals and confidence ranges.
