Haphazard sample
If the population is not evenly dispersed then the sample may unfortunately come from a section that is not typical of the population. That means the sample will not be representative of the population and so any estimates for the population, based on sample statistics are biased and therefore unreliable.
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
satistics is knothing but, sampling character is called as statistics By P.Sugapriya paranjothi
Sampling distribution in statistics works by providing the probability distribution of a statistic based on a random sample. An example of this is figuring out the probability of running out of water on a camping trip.
SE stands for ''standard error'' in statistics. Thanx Sylvia It is the same as the standard deviation of a sampling distribution, such as the sampling distribution of the mean.
Advantages of Poisson sampling method include its simplicity and ease of application, as well as its ability to provide unbiased estimates of population parameters. Disadvantages may include potential underrepresentation of rare events or small subgroups in the population, as well as the assumption of random and independent sampling.

conclusion to the statistics sampling
If the population is not evenly dispersed then the sample may unfortunately come from a section that is not typical of the population. That means the sample will not be representative of the population and so any estimates for the population, based on sample statistics are biased and therefore unreliable.
The answer depends on the cost of the various options and the required accuracy of the reusults.
The answer depends on which parameters are to be calculated.
B. The sampling error
they must be correct and they must be the right kind of sample

The sample is of little use in making estimates for the population as a whole unless it is known exactly how it is non-representative.
