Sampling and populations

Mon, 01 Jan 0001 00:00:00 +0000

We sample for a very practical reason. It’s usually impossible to get information on the whole population, so we use a sample to make inferences about the population. In our case, the population is typically all sites in a stratum or all sites – in all strata – at the scale of an entire park. Typically, the inference we seek entails three questions.

What’s the best estimate of the population mean?

We can generate a sample mean, \(\bar{x}\) , from our sample. This is the best estimate of the population mean.
