DATA COLLECTION METHOD
Questionnaire surveys were chosen after considering other research techniques because it is common method to collect primary data, however, the question must be simple, self-explanatory, clearly structured and easy to understand since we will not be with them to explain the questions. Other reasons for choosing as follow:
i. Primary data need to be collected from a representative sample of a population in order to make generalizations about the factors that influence job satisfaction. ii. This type of surveys is most suitable to study attitudes and behaviors iii. The answers are standard and uniform so that allow the researcher to do evaluation and distinction
iv. Survey results are fairly reliable and accurate
v. Surveys

Every question in the questionnaire should be linked to the research questions and hypotheses, however, there is no commonly accepted principle of questionnaire design. There are a few suggestions from research publication of marketing for setting a general policy in order to govern every step of the design process. The process …show more content…
Probability sampling will be the most appropriate method to use if the objective of the research is to estimate the population as a whole. Zikmund (2003) stated the benefit of using the probability sampling. In this method, every member of the population has an equal chance of selection, which minimizes selection bias and improves accuracy. There are many types of probability sampling:
i. Simple random: Researchers allocate each member of the population a number and then select sample unit randomly. Samples are based on equal chance. ii. Systematic: Researchers use the natural order of sampling frame, select a random starting point, and then select items at a pre-selected interval. iii. Stratified: Researchers divide the population into groups and randomly select subsamples from each group. Variations include proportional, disproportional, and optimal allocation of subsample sizes. iv. Cluster: Researchers select sampling units randomly and survey all members in the group.
v. Multistage: Researchers select smaller areas in each stage and integrate the first four techniques above

c. A researcher is planning to analyze the effect of multiple strategies to teach fractions to 6th – graders in Happy Valley School District. She assigns each 6th – grader a number and uses a random number generator to select students for each of her research groups. Ans. Systematic Sampling because she assigns a random nth number to select students for each of her research groups.
Thus, before reaching any conclusion it is necessary to get more information about survey. Thus, all the above mentioned questions can question conclusion of the argument. The answers may support or may not support the argument. Therefore, before reaching any conclusion, first gather all the information required to answer above questions, which will help to reach on right
In the first stage of the sample, the researchers selected a random sample that was proportionate to the size of the school, from the American Council on Education’s list. Next, within each participating school, they picked a systematic
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.
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
If it is understood how parental incarceration affects children, adult imprisonment of these children may be preventable in the future. It is expected to observe a change in behavior or psychological health due to the absence of one or both parents. If a change is apparent, it would be useful to know if it was due to the incarceration or other factors. Despite the reason, the goal is to discover exactly how a parental incarceration affects the child’s future and whether or not they face a heightened risk of being incarcerated. Risks for children whose parent(s) had been incarcerated includes: increased delinquency and possible incarceration if it persists, aggression, physical or sexual abuse, depression, antisocial behavior, anxiety, trust

Next, since this is a phenomenological study criterion sampling works the best because this sampling focuses on people who have experienced the same phenomenon (Creswell, 2013). As far as the fidelity and trustworthiness aspect, the criterion sampling is useful for quality assurance (Creswell, 2013). In addition, I was considering 10 participants using open-ended questions and an audiotape.
1. NURSING RESEARCH Research is a detailed study into a particular problem, issue or concern using scientific method. It could also be defined as gathering information usually to answer a particular question or problem. Nursing research is a systematic study that provides evidence used to support nursing practices.
So according to the survey, the majority of people interviewed agreed with my
Although I have not had a chance to help or conduct a research, I think all methods of study contain a bit of bias. After, researchers and scientists are human. Anyhow, random assignment is a useful technique yet, it is important to consider other possible methods of assignment and to work out which one will beneficial for the study the most before committing to one type of method since there many types of samples. For instance, if the experiment were to look at the treatment of depression using Electroconvulsive therapy (ECT) treatment and drug therapy, it would be hard to randomly allocate the groups. Studies have shown that people with severe, chronic depression recover better than those with mild depression when it comes to ECT treatment.
Across all four of the surveys, all of my results were consistent,
I believe the results were an accurate snapshot of the general population
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.
