QMB 3200 UCF FINAL VOCAB ALREADY PASSED Parameter A numerical characteristic of a population, such as a population mean μ, a population standard deviation σ, a population proportion p, and so on. Target population The population for which statistical inferences such as point estimates are made. It is important for the target population to correspond as closely as possible to the sampled population. Sampled population The population from which the sample is taken. Sampling dis...
