A fundamental part of carrying out a statistical study of any kind is to obtain reliable
results, for which the greatest possible amount of data is normally needed. But it was
generally almost impossible or impractical to carry out some studies on a whole
population, for this the solution is to develop the screening study in a subset of the said
population in a sampling (Polit & Beck, 2004). The “what or who”, that is, the
participants, objects, events or communities of study are the units of analysis of an
investigation. Their choice depends on the research approach and the scope of the
study.
First, we will determine the sample. This will be the part of a selected population on
which data will be collected, and that has to be precisely defined or delineated
beforehand, the sample must be statistically representative of that
population (Heale & Twycross, 2015). For this, we can use different methods, such as
Probabilistic sampling methods, which includes, simple random sampling, systematic
random sampling, stratified random sampling, random cluster sampling, on the other
hand, we will have non-probabilistic sampling methods, which include, quota sampling,
intentional sampling, and casual sampling (Taherdoost, 2016).
In the probabilistic samples, all the elements of the population have the same
possibility of being chosen, the sample is obtained using statistical methods which will
result in a representative quantity of the population. Probabilistic samples can reduce
the error size and in turn, can measure it. In non-probabilistic samples, the choice of the
elements does not depend on the probability but on the characteristics of the
investigation or who makes the sample (Taherdoost, 2016). Here the procedure is not
mechanical or based on mathematics, but the decisions of those who carry out the
research, obeying various criteria. So in my personal opinion, I would be more inclined
to the probabilistic samples since they would be making us with greater veracity to the
real values of our studio.

Sampling Methods and or specific samples are selected or determined based on the research you are
conducting. When
you have determined the type of research you want, you must then
have a list of goals you you are expecting to meet. This will drive the precision and or
information collected and the result would be viable if all the conditions have been
met. If you do not plan properly you may have too small of a group or specific criteria
that is not met and the end result will not be useful (Polit, D.F. and Beck, C.T. (2004)
Nursing Research: Principles and Methods. 7th Edition, Page 240)
I believe that an effective method is observation which is also broken down to event
sampling. This way you are able to group participants that meet a particular criteria
that may be observed and you have based your outcome on a comparison or off
personal knowledge for the event. I will also be organized to where anyone following
the research can interpret and understand as well. (Complex Needs)
In closing, sampling methods is another great tool used in conducting research. It assist the
researcher in collecting and organizing a systematically to make sure that all data is effective and
the sample groups being used are big enough to the have a valuable and accurate outcome.
