population -group statistically sampled.
Business can randomly sample a group of people in the populations. They can also call for volunteers such as setting up a focus group.
It is a sampling method in which units are selected based on easy access/availability. The disadvantage of convenience sampling is that the units that are easiest to obtain may not be representative of the population. For example products on top of a box of parts may be a different quality from those at the bottom, people who are at home when the market researcher calls may not be representative of the entire population. It is also called as Accidental Sampling.
Hi, 1.The main advantage of Systematic sampling over simple random sampling is its simplicity. It allows the researchers to add a degree of system or process into the random selection of subjects. 2.Another advantage of systematic random sampling over simple random sampling is the assurance that the population will be evenly sampled. Disadvantage The process of selection can interact with a hidden periodic trait within the population.
Population sampling is the process in which a group of individuals are selected to represent a population for the purpose of statistical analysis. Population sampling allows the analyzers to learn about a population without studying every individual in it.

conclusion to the statistics sampling
The process of selecting representative elements from a population is called sampling. Sampling involves selecting a subset of individuals or items from a larger group in order to draw conclusions or make inferences about the entire population. Various sampling techniques, such as random sampling or stratified sampling, can be utilized to ensure that the selected elements accurately represent the population characteristics.
Describe how more complex probability sampling techniques could provide samples more representative of a target population than simple random sampling Illustrate your answer with an information technology example.
Haphazard sample
Inferential statistics
In systemic sampling, we select some starting point and then select every kth (such as the 50th) element in the population. Per Elementary Statistics by Triola, page 24
There are situations where collecting information from every member of a population is difficult, impossible or pointless. In such cases sampling is used. The rationale behind this is that, if the sample is selected properly, then statistics based on the sample will be good approximations for the corresponding measures of the population as a whole.Incidentally, a census is pointless when testing is destructive. If a baker tested/tasted every cake that was made, there would be none left to sell!
