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.
Scientific design is always better.
In the process of developing a sampling design for this study, there are some critical factors you should consider. Explain five of these factors.
The sampling design you are referring to is called "purposive sampling" or "judgmental sampling." In this approach, researchers select individuals based on specific criteria or characteristics that align with the study's objectives, often to ensure that certain controls are maintained. This method allows for a focused investigation of particular traits or behaviors, but it may introduce bias since the sample is not randomly selected.

Sampling theory is a statistical framework that focuses on the selection of a subset of individuals or items from a larger population to make inferences about that population. It establishes the principles and methods for determining how samples should be drawn, ensuring that they are representative and can yield reliable estimates of population parameters. Key concepts include sample size, sampling methods (like random, stratified, and cluster sampling), and the implications of sampling error. This theory is essential in fields such as survey research, quality control, and experimental design.

sample design
IEC 60410 specifies guidelines for the sampling of bulk materials, focusing on the design of sampling systems and procedures. To load samples according to this standard, you first need to define the sampling plan based on the material's characteristics and the intended analysis. Then, implement a systematic approach to collect representative samples, ensuring that the sampling equipment is properly calibrated and that the samples are stored and transported in a manner that preserves their integrity. Finally, document the entire process for traceability and compliance with the standard.
