Another advantage of qualitative research is that it gives more thorough data in the shape of complete descriptions in written form or visual evidence, such as photographs. This type of research looks at context and social meaning and how it affects individuals, which is beneficial mostly in the social sciences. The disadvantage of qualitative research is the interpretation of researcher s’ own biased view, which can misinterpret the facts. Another disadvantage is that this research method is very time consuming. Quantitative research allows assessing and analyzing data.
What kind of research method you will use depends on what kind of report you are writing, if you will dig deep into the research or if you will do more of a basic research. Qualitative research is a method that is focuses on the “why” and “how” of the report, while the quantitative method focuses more on the numerical part of things and answers questions such as “How much?”, “ How many?” and How often?”. The main differences are qualitative research were created in the human and psychological sciences and has a lot to do with theories based on hermeneutics, phenomenology, and sociology. It focuses more on words and how people feel about certain situations. These have to do with human interpretation and personal experience you can collect this information through interviews.
“Examine the reasons why some sociologists choose to use structured interviews when conducting research” Structured interviews are like questionnaires, as they both involve asking participants a standardised set of questions which are usually closed ended questions with pre-coded answers. However within a structured interview the questions are read out loud to the ‘interviewee’ and the answers given are filled in by the researcher. Structured interviews give quantitative data as the questions have pre-determined answers. This makes them very reliable. This means that structured interviews will appeal to positivists as they like sociological methods which gain reliability, gain quantitative date and can cope with a large sample size.
A deduction is evidence found through simple research to narrow down a more informative form of a theory; you can say it is an official theory or scientific guess called a hypothesis, with more evidence of the issues a hypothesis is formed from a theory using deduction. The next step will be achieved though the operationalization process in order to achieve a research design, the operationalization process puts number values on the research and may consist of precise measurements in order achieve a good research design ( found
STAT 1008 Assignment One Question 1 (a) The main purpose of statistics is that when the size of the population is not manageable, a sample of manageable size should be drawn from the population. While we are ultimately interested in some numerical aspect of the population, we also hope that some numerical aspect of the sample would reflect the numerical aspect of the population that we are interested in. Thus, there is no need to use census. (b) Stratified sampling is recommended. Stratified sampling is commonly used in the scenario described in the assignment spec.
: conducting interviews, surveys, leading the focus, etc.) Quantitative research places numerical values on information collected. This type of research generally deals with numbers and facts, like statistical data and the analysis of statistics. The information can be mathematically measured and compared if desired. The research and data is strictly fact-based and not estimates or opinion.
Hypothesis Testing and Confidence Intervals Utilizing the data provided AJ Davis Department Store performed Hypothesis Testing and Confidence Intervals performed to determine s the assumptions made are correct or incorrect. As with any Hypothesis test we must know some basic factors, such as sample size, sample mean, sample standard deviation, and you must have an hypothesized mean. Either through mathematical formulas, or by employing programs such as MS Excel and or Minitab, we can test whether or not the to reject or accept the hypothesis. For all subsequent testing, both MS Excel and Minitab will be utilized to determine whether or not accept or reject the null hypothesis. Assumptions are as follows: 1.
The main difference is that in the interview, the questions are read out and the answers are filled in by a trained interviewer rather than by the interviewee. There are many practical advantages for the use of a structured interview for example training interviewers is relatively straightforward and inexpensive, since all they really required to do is follow a set of instructions. Moreover surveys that use structured interviews can cover quite large numbers of people with relatively limited resources because they are quick and fairly cheap to administer. Structured interviews are suitable for gathering straightforward factual information such as a person's job or age. Finally the results are easily quantified
The information is easily translated into simple charts and graphs due to the fact the information provided are in statistical number form (Melnyk & Fineout-Overholt, 2011). Not having a large enough sample is a imitation to quantitative research. Before the study is started, large samples are required for quantitative studies. Validity, accuracy, and projectability all can be affected by the misuse of sampling, which can also limit the research. Another limitation was not having enough give, which can cause statistical error because the research has short interviews (Winters et al.,
The question that should be asked is what method should be chosen so that it will be the most cost and time effective? Small Groups VS Individual Expert as Problem Solving Small groups tend to surpass individual experts when alternative solutions are present. Due to the fact that small groups consist of multiple bodies, they can input there own specific experiences and unique knowledge into the task at hand thus coming up with an, if not better, answer than that of the individual. Group work causes less strain to the mind and well as it is a lot less time consuming. Typically higher quality work is present with multitudes of solutions.
