Convenience Sampling Method

875 Words4 Pages

What is sampling?
When a survey has been generated and tested carefully, it is time to send out the survey in order to collect responses. The distribution procedure and data collecting phase, is one of the most important part of the survey processing which has a big influence on the further analysis. Sometimes, the entire population will be sufficiently small and researcher can consider an obvious way to perform that by sending out the survey to all the possible individuals and then waiting for their responses. This type of research is called a census study. Although this method seems to be easy and good, it is not applicable and efficient most of the time, especially when the target population is huge or simply not entirely reachable.

As it is obvious from the title, sample is selected because they are convenient to be selected via selecting whatever persons can be most easily access to accomplish the survey. Convenience sampling is mostly used in preliminary research efforts in order to achieve a gross estimation of results without devoting the required cost and time to gain a random sample.
Judgment sampling: this method is a common non-probability sampling method in which the researcher decides which members of the entire population should be selected based on his/her judgment. Since the researcher’s judgment is the criteria for selecting sample, it is necessary that s/he ensures that the selected sample is an appropriate representative of the entire target population and if it is needed some alternative justification for representativeness may be applied.
Quota sampling: this method is the non-probability version of the stratified sampling i.e. the researcher determine the stratums firstly, then one of the non-probability methods like convenience or judgment sampling will applied in each stratum. The difference between quota sampling and stratified sampling is that the randomness is not included in the first one. This method is widely used in non-probability market research

    One aspect of public health research method that I learned is that measurement is central to quantitative research because it provides the fundamental connection between empirical observation and mathematical expression of quantitative relationships. I also learned that the goals and techniques associated with probability samples differ from those of nonprobability samples. If we want to get results that are valid for the whole study population, we should know how to draw a sample in such a way that it is representative of that population. But it is not necessarily that nonprobability samples are not representative of the population. It means that nonprobability samples cannot depend upon the rationale of probability

    Misfit or monster? serial killers, although uncommon, have been around since the beginning of time, even if they didn't have a name. Robert Ressler came up with the phrase "serial killer" to get rid of the title of "stranger killings' ' and to show how repetitive killers are. Over the years profiling has been used to catch these killers, as they have been leaving patterns. It was used as an investigative tool in the 1960s when James A. Brussel helped New York police catch the "Mad Bomber" where profiling made its first appearance.

  • The Pros And Cons Of The Reid Technique

    911 Words  | 4 Pages

    In early interrogations it was common for police officers to use physically abusive interrogation techniques such as the rubber hose to convince suspects to confess to a crime, whether they are innocent of guilty. Fred Inbau came up with a different technique that relied on presenting a large amount of fabricated or true evidence to get the suspect to confess. This technique was very effective in getting confessions, it has an 80% confession rate. Unfortunately, some of the confessions are false confessions, we do not know how many exactly. The first step of the Reid Technique, a similar coercive technique to the one Inbau devised, was to watch the suspect and determine whether or not he or she is lying during the interrogation based on behavioral analysis; which is severely flawed and does not actually help us determine if someone is lying.

    Surveying would then be pushed into actual realization with asking a specified number of both civilians and officers for a fair result on opinions. After surveying the next research method, I believe best for this research topic and the discussed views quantitative research as statistics relate well for research. Numbers are a large part of facts, having percentages and other statistics increase accuracy on the studied topic, and a better understanding on the aspects the numbers cover. When researching this topic I would put these methods into use along the way, with every step. So, that I might be able to better understand and so that those who read or participate in the survey and paper will understand.

  • The Pros And Cons Of Fingerprinting

    1172 Words  | 5 Pages

    Fingerprinting is method based on the uniqueness of the skin pattern - that is, each person has a completely individual pattern of papillary lines. These patterns do not change throughout life and have the property of recovering from damage to the skin in its previous form. On the one hand, this method almost completely eliminates the mistake, and on the other hand it is very cheap and easy to use (in contrast the method of identification of a person by DNA). Fingerprinting allows: 1) to identify the person who left the prints, according to the general and particular features of the papillary pattern displayed on them; 2) to exclude individual from among those who have touched the object; 3) to narrow the group of individuals suspected of the particular crime (for instance, provided that the imprint shows traces of a scar, a burn, a wart or some other distinctive feature).

    The three descriptive research methods that I will discuss are Naturalistic Observation, Survey, and Case Study. Naturalistic Observation is a research method in which people or animals are observed in their natural habitat without any controls or variables. This type of research method may be conducted if you want to see how people truly act without being watched. For example, this research method may be used to determine who are healthier shoppers, men or women? The researcher would go to a food store and take count throughout the day of how many men and women he finds in the fruit and vegetable isles, and how many he find in the snack isles.

This can be seen from the simulation Ramada did, during the “Grand Hotel Opening” they asked their employees, this includes staffs and management, some people from headquarters and the property owners. These are the people they are interested in and they are the people that Ramada wants to do research on. This sampling method is appropriate because it focuses on the population the researches interested in studying. It is more necessary rather than conducting the research on the customer, they instead focus on their own management to improve their inside quality.
