1. Suppose you have been assigned to estimate tree height in a population of trees that lie within a 150,000 hectare forest. Assume you will sample within 1/10 hectare plots.

a. Outline the steps you would take to estimate tree height in the population. In your outline, define your sample unit. Explain how you would minimize bias and avoid pseudoreplication. b. Show an example (with paper and pencil, not R) of what your data frame would look like once the data were collected. Show example calculations of how you would:

i. Estimate mean tree height.

ii. Estimate variability within your sample size
