Sampling is a method of selecting experimental units from a population so that we can make decision about the population.
Sampling design is a design, or a working plan, that specifies the population frame,sample size, sample selection, and estimation method in detail. Objective of the sampling design is to know the characteristic of the population.

Which is better sampling designscientific or non-scientific?
Scientific design is always better.
Adjacent angles in a sentence?
Adjacent angles define the shape and perception of the design.
Why the random sample is important in design of experiment?
There are circumstances when it is important and others when it is not. If, for example, you wanted a sample of all schools in the country, it would make more sense to go for cluster sampling. A lot of market research work will require quota sampling. So the supremacy of a random sample is a myth.
What do you mean by sampling procedure?
To determine which, of a number of samples, is best for the application that is required. A single example of a quantity of mass produced items extracted for analysis, to ensure that the remainder are of design specification
What is the difference between double sampling and multiphase sampling?
DOUBLE SAMPLINGDefinition:A standard form of sample design for industrial inspection purposes. In accordance with the characteristics of a particular plan, two samples are drawn, n1 and n2, and the first sample inspected. The batch can then be accepted or rejected upon the results of this inspection or the second sample be inspected and the decision made upon the combined result.Context:The term has also been used somewhat loosely for what is called multi-phase sampling and the two-stage version of multi-stage sampling. There is a further usage whereby a first sample provides a preliminary estimate of design parameters which govern the size of the second sample to achieve a desired overall result.MULTI-PHASE SAMPLINGDefinition:It is sometimes convenient and economical to collect certain items of information from the whole of the units of a sample and other items of usually more detailed information from a sub-sample of the units constituting the original sample. This may be termed two-phase sampling, e.g. if the collection of information concerning variate, y, is relatively expensive, and there exists some other variate, x, correlated with it, which is relatively cheap to investigate, it may be profitable to carry out sampling in two phases.At the first phase, x is investigated, and the information thus obtained is used either (a) to stratify the population at the second phase, when y is investigated, or (b) as supplementary information at the second phase, a ratio or regression estimate being used.Two-phase sampling is sometimes called "double sampling".Context:Further phases may be added if desired. It may be noted, however, that multiphase sampling does not necessarily imply the use of any relationships between variates x and y. The expression is not to be confused with multi-stage sampling.
Error is serious Sampling error or non sampling error?

Who is the author of total enumeration sampling design?
Total Enumeration Sampling Design is a method used in research and typically doesn't have one specific author. It is a technique that involves studying and analyzing an entire population rather than a sample. It is commonly used in fields such as epidemiology and census studies.
