3 Terms and definitions
The following terms and definitions defined in GB/T 36296-2018 apply to this document.
3.1 Estimate
The statistical inference value of the population attribute through the sample.
[GB /Z 33451-2016, definition 3.1.18]
3.2 sample
A subset of the population composed of one or more sampling units.
[GB/T 3358.2-2009, definition 1.2.17]
3.3 sampling
The act of taking or forming a sample.
[GB/T 3358.2-2009, definition 1.3.1]
3.4 Sampling unit
After dividing the whole into each part.
Note 1.Sampling units can be graded, the overall is composed of primary (sampling) units, each primary (sampling) unit is composed of secondary sampling units, and so on.
Note 2.Rewrite GB/T 3358.2-2009, definition 1.2.14.
3.5 Simple random sampling
Take n sampling units from the population to form a sample, so that all possible combinations of n sampling units have equal probability of being selected.
[GB/T 3358.2-2009, definition 1.3.4] […]
