Comparison of Fixed-Radius Circular Plot Sampling with Simple Random Sampling
David O. Yandle, Harry V. Wiant · Forest Science · 1981
Abstract Sampling by random selection of fixed-radius circular plots is shown to differ in a fundamental way from simple random sampling. An appropriate sampling population for circular plot sampling is given. Differences in sampling probabilities and estimators for simple random sampling and fixed-radius circular plot sampling are given. The sampling efficiencies of the two techniques are compared by evaluating variances of their respective estimators of the population total. Forest Sci. 27:245-252.
