Population
Parahoo (1997:218) defines population as “the total number of units from which data can be collected”, such as individuals, artefacts, events or organisations. Therefore a research population is generally a large collection or complete set of elements of individuals or objects that are the main focus of a query. (Winer: Brown, & Michels :1991).
For the purpose of this study, the researcher will select employees and senior managers working at the Auditor General’s Office . The office of the AG has a population of 95 members of staff including the top three executives. The researcher will selectively and purposely choose participants who will be more likely to provide valid information about the research problem. The

A sample is therefore a representative part of the entire population or an extract thereof from which to generalize back to the whole population. Sampling is the process by which inference is made to the whole population by examining a part of the population (Dickersin:1990). The purpose of sampling is to provide various types of statistical information of a qualitative or quantitative nature about the whole or entire population by examining a few selected units. The sampling method is the scientific procedure of selecting those sampling units which would provide the required estimates with associated margins of uncertainity, arising from examining only a part of the population and not the whole or entire population. (Tashakkori & Teddlie 1998: 47), As mentioned above the office of the AG has a population of 95 members of staff including the top three …show more content…
It will contain both the closed and open ended questions. In-depth interviews or unstructured interviews are informal and the researcher chose this technique because it gives the researcher scope to explore in depth a general area of interest. There is no predetermined list of questions to work through when in-depth interviews are used, although the interviewer needs to have a clear idea about the aspect or aspects to be explored. The interviewee will be given the opportunity to talk freely about events, behaviors and beliefs in relation to the topic area (Saunders et al, 2007:312).The interviews will allows the researcher an opportunity to establish good rapport with the respondent and explain the purpose of the interview. The interviewer is able to add clarifying remarks whenever the respondent fails to understand a
To be representative the characteristics of my sample population have to match those of the entire target population. In this study, I have to make sure that the right variety of people is interviewed. If the sample is not representative it can be subjected to biases. It could be that with me picking only African Americans and Latinos I risk over-representing these groups while under-representing other minority groups which can be a valid argument. In order for this to be representative,
As a nontraditional student, I found the article “Mapping the Misunderstood Population of Adult Students”, (Ashburn, E. 2007) to be a close representation of myself as an adult student. Financial aid is one of many areas that seems to fall short for the adult learner. The decision to return to school is different from that of a traditional student. As a forty-eight year old woman with a productive career, still raising a family, and many social obligations, going to college was a decision that would affect all of these
A superintendent wants to do a study on poverty level versus student achievement levels in elementary students. His district has 18 elementary schools. He randomly chooses 6 of those schools, then includes all students from these 6 schools in his study. Ans. Convenience Sampling
subsection{The sample} label{subsection:CHILD_Sample} In wave 1, the survey consists of 18,552 children. The effects of sample selection on the size and on the characteristics of our final sample are shown in Table ef{tab:CHILD_SampleSelection} for each step in the selection process, we display the average characteristics which we will use throughout the paper and which will be explained in this section.
Before the survey questions relevant to the topic are presented, the first 3 questions cover background information that i felt was necessary for this topic. Public attitudes involve the public as a whole, including families, different ages, and therefore it is important to gather this personal information about the respondent. Public attitudes as a whole are important in this topic as victims of crime tend to be the more vulnerable groups, such as the elderly, females, and young people. From this their response to the reintegration of offenders maybe substantially different to those of the less vulnerable groups. Additionally, offenders most likely to be reintegrated into society are those who have committed sexually orientated crimes and as a result of this, women and children are most at risk of being victims of these crimes (Rubin, 1984).
Although chapter 8 is not my favorite chapter in the book but it is a very important chapter. When it comes to the understanding of statistic and different methods one can use when conducted a survey research, chapter 8 layout multiple ways one can go to reach a meaningful result. For example, when conducted a research, instead of survey the whole population to find results or to draw conclusions based on the study, chapter 8 suggested that one should used a sampling because that will make it more easier and possible to select a few hundred or thousand people within the population for the study; and that way, one will discover things that apply to numerous people in the population who were not a part of the study. Talk about sampling, there
A populace can be either vast or little, contingent upon what you 're examining. When you utilize descriptive statistics, you need to have the whole populace available to you, since descriptive investigation gives you the properties of the populace all in all, such the mean or the supreme deviation. These are called parameters, and with just a little piece of the populace you can 't all of a sudden thought of the parameters. Inferential statistics becomes possibly the most important factor when you don 't approach the whole populace. For example, in the event that you needed to locate the normal of the whole school 's test scores you may think that its incomprehensible for you to do as such with a specific end goal to get the information that you
3.3.11 Purposive sampling defined Ritchie & Lewis (2006:78) states that purposive sampling is precisely what the name suggests. Members of a sample are chosen with a 'purpose' to represent a location or type in relation to a key criterion. This has two principal aims. The first is to ensure that all the key constituencies of relevance to the subject matter are covered. The second is to ensure that, within each of the key criteria, some diversity is included so that the impact of the characteristic concerned can be explored.
Evidence Open Ended Questions Some of the many benefits of an open ended question are that it allows an infinite number of possible answers, collects more detail, it allows the person to learn something they didn 't expect to know, get adequate answers to complex issues, it encourages creative answers and self expression, and gives the person an understanding of how the respondents thinks. According to the transcript provided in this case study, there are relatively few occurrences in which open ended questions were used for eliciting useful information. This is expected to a limited extent of the work culture that the call center manager, Thomas has imposed in his location. The first situation where evidence of an open ended question was demonstrated
Demographics in the United States have been undergoing very rapid changes over the last decades. Recent political turmoil in Asia, Africa and Latin America have encouraged people from those areas to immigrate into the United States, and years before that, it was mostly Southern and Eastern Europeans along with European Jews and Irish people who immigrated due to the political conflicts in their respective countries. With such a complex population make-up, a turbulent history of tension and conflict amongst the country’s diverse ethnic, religious, and socio economic groups can be expected. Not only is conflict over social justice issues an extensive part of American history, ever since the foundation of the United States there has been conflict over who, exactly, is to be considered an American.
Additionally, the systematic approach offers the researchers and the statisticians with a level of control and a sense of process (Kalton, 2014). Therefore, it is precisely beneficial for the studies with a narrowly established hypothesis. The systematic sampling technique normally makes sure that there are high levels of representativeness; hence it does not require usage of a table representing random numbers. The other merit of systematic sampling is that in a clustered selection, a situation where the randomly chosen samples are not close together in the population, it is typically eliminated by the approach of systematic sampling. Another merit of routine sampling is that it has the low-risk
This can cause not only the results of research to be skewed but also how data is collected could be
David Kindig April 6, 2015 The term population health includes group of individuals. Traditional population health definition restricted on geographic populations, new terms we can say healthy people are having less medical background. In nationas pupulation we can include pregnant woman, every childbirth is safe and every young person 's potential is fulfilled or not?
The use of open-ended, in-depth interview questions allows for the generalization of findings and allows for studying an organization or entity in-depth within a limited timeframe (Yin, 2014; Dumez, 2015). The qualitative multiple-case study methodology will provide narrative illustrations accompanied by detailed descriptive stories and will uncover trends that will help respond to the study purpose (Lewis, 2016; Kienstra & Heijden,
Non-probability Sampling Method: Sampling method that require the conductor to choose a subset of population they are interested in researching. 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.
