Cluster sampling examples. Example 1: Assume that a study with relatively large square fixed area plots of 50 m x 50 m had been carried out, on which all tree positions were mapped. Because the individual plots were relatively large, there were only resources available to measure \(n=10\) sample plots.
Thread: Pooled sample. I want to discuss why and when one should use pooled sample. Pooled samples are generally used to save on analysis time and costs by reducing the number of samples six-fold. I personally don't like the practice, as it can hide flawed tablet results by averaging them with other units. It also doesn't have any account for variability of batches.
