MKTG 320 Chapter Notes - Chapter 11: Simple Random Sample, Sampling Frame, Sampling Error
Document Summary
Sampling: the process of obtaining information from a subset of a larger group. Population: an entire group of people about whom information is needed also called universe or population of interest. Census: a collection of data obtained from or about every member of the population of interest. Sample: a subset of all the members of a population of interest. 7 steps to summarizing a sampling plan: define the population of interest, choose a data- collection method, identify a sampling frame, select a sampling method, determine sample size, develop operational procedures, execute the operational sampling plan. Sampling frame: a list of population elements from which units to be sampled can be selected or a specified procedure for generating such a list. Random digit dialing: method of generating lists of telephone numbers at random. Probability samples: samples in which every element of the population has a known nonzero likelihood of selection.
