Representative Sample - ✔✔Closely represents relevant characteristics of
population under consideration
Probability Sampling - ✔✔Uses random device to decide which members of
population instead of human judgment
Simple Random Sampling - ✔✔Each possible sample has equal chance (with and
without replacement)
Systematic Random Sampling - ✔✔Provides sufficient coverage when
information about sub populations is required
Cluster Sampling - ✔✔Useful when the members of population are widely
scattered
Stratified Sampling with Proportional Allocation - ✔✔Obtaining simple random
sample of size proportional to population in each stratum
Experimental Design - ✔✔Uses principles to conclude that differences in results
of experiment not reasonably attributable to chance are likely caused by
treatments (Control, randomization, replication)
