Sampling method

For a quantitative research to be effective the right sampling method that suits the subject in question should be considered. In the study sampling, we commonly use the probability and non-probability sampling method. The probability sampling allows the items or the members of the frame have the right to be selected for the study while the non-probability does not rely on the use of randomization techniques to select members. Perhaps the probability sampling will give the best result and will ensure a quality research work. Therefore, the research subject will be influenced significantly by the three principles. For example, if the research question involves humans like find out whether the therapeutic decrease depression in the living home residence (Levy, 2013).

The Advantages and Disadvantage of probability sampling

Since this sampling allows each member of the population to be selected randomly, each one has a chance to be selected hence making the process probabilistic. This sampling method has various advantages like its cost and time efficient; it has the lesser degree of judgment compared to the non-probability, it is a comparatively easy way of doing sampling. Similarly, it has demerits such as it is redundant and monotonous to work with this kind of sampling since the surveyor will be forced to do a repetitive sample to ensure its effectiveness (Ampt, 2007).

The three ethical research principle

The first principle is the Beneficence which refers to the duty on the part of the surveyor to maximize benefits for the individual participants and the society while reducing the risk of harm to the individual (Levy, 2013). The second is the autonomy which refers to the right of the individual to determine what activities they will and those that they will not participate. Lastly is the justice which demands equitable selection of the members hence avoiding participant group that will affect the participation. In addition to this, we understand that the role of the researcher is to make sure that the right sample is taken and the subjects are not threatened.
