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.
Example 1: Find the Descriptive Statistics when the data set represents a Sample using your TI-83 or TI-84 calculator. 1  Sample mean. 2  Sample standard deviation. 3  Sample size.  Minimum value of the 1  sample. Q1 of the Sample.  Median of the 1  sample. Q3 of the sample.  Maximum value of the 1  sample. Sample variance. Use 1-Var  Stats.
