In quantitative research, variables are identified and defined, and then relevant data is collected from study participants. A strength of this type of research is that the data is in numeric form, making it easier to interpret. It also studies the relationship between independent and dependent variables and can address questions such as does a relationship between variables exist, what is the direction of the relationship, how strong is the relationship between the variables, and what is the nature of the relationship. To be able to discover and answer the cause-and-effect relationship is a strength of quantitative research. Lastly, in quantitative research, the study can either be experimental or nonexperimental, meaning clinical trial or observational study, allowing for different types of research studies to be conducted. And the steps to a quantitative study is resonantly linear and broadly similar across studies (Polit & Beck, 2017). …show more content…
“Quantitative research is conducted in a context of previous knowledge” (Polit & Beck, 2017, p. 54)., which could limit a researcher based off their amount of previous knowledge on the subject being studied. And the researcher collect data from a sample size of a population. The sample’s adequacy is assessed by its size and representativeness. (Polit & Beck, 2017). A small sample size could limit the validity of the

U6: Establishing audiences Quantitative: Quantitative research is a form of research where people are asked something with a simple answer that can be quantified afterwards to represent a larger group. This type of research has simpler answers (yes or no) than qualitative which has more complicated answer (such as a paragraph of text) that can not be quantified but tells a lot more information with 1 answer. Quantitative research is quicker and easier to gather result. Quantitative research can be used for things such as seeing how much of the population in the UK like corn flakes. They would do this by making a survey with a simple answers for the person being surveyed to choose from, the people doing the survey would be people chosen at random
Initially, l clearly defined my goals and objectives of the data collection to ensure the data gathered will be accurate, credible, can be repeated, reproduce able. Then reach an understanding and agreement on the operational definitions and methodology for data collection. As a student there is often a marked divide in my mind between using a qualitative or quantitative approaches. 8.2 Social Concept: Socially, data gathered about a phenomena contain real information and it is useful to the improvement efforts in the society. Good data collection planning prevents errors that commonly occur in data collection process, it saves time and money that otherwise might have been spent on repeated or failed attempts to collect useful data.
Each article was logical in its presentation of results and refrained from outside input. This effectiveness characterizes Milgram and Zimbardo as credible sources and well-rounded
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
In their articles the use of statistics was something that was good. When people see numbers it’s a good way to get the people 's attention. People react faster to numbers then when you try to explain it to them. A rhetorical strategy the authors of this paper used were ethos.
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.
Quantitative research looks at interventional studies and outcome based research. It is the type of study one can do a lot of statistical analysis and can include, clinical trials, case-control studies, case reports, and clinical practice guidelines. Qualitative research is really done to understand the human behavior and how people are responding to their situation. Type of qualitative research which are mostly done in nursing or social sciences include, ethnographic group, grounded theory. One need to make sure that the patients are having a good experience with the care they are receiving.
As quantitative data would not be robust enough to explain complex issues. for e.g. Quantitative data would not allow children to explain their choices. However, qualitative data has some disadvantages in this research. For example, because of the central role played by Corsaro in the generation of data, it is not possible to replicate qualitative studies. Also, contexts, situations, events, conditions, and interactions cannot be replicated to any extent.
SECONDARY RESEARCH Secondary research is also known as desk research and it consist the data which has already been produce it can be quantitative, qualitative or historical also it can be seen as internal data and as well as external data. Secondary research is the process which involves collecting data it may be originator or distributor of primary research, secondary sources include documents, letter, diaries, autobiographies and referencing other forms of research and quotes. KFC they are able to save money and time through having enough employees who are able to do most on the work which saves time as well as money because they will serve more customers in a short period of time. KFC are able to get information and access information
Methods For our research, we performed a survey that included eight questions that pertained to gender, age, relationship status, sexual activity, attributes for a potential partner, and the desire to eventually get married. We distributed our survey amongst college students that attend Bakersfield Community College (BCC) located in Bakersfield, Ca. In the (JOAQUIN) class, there were seven males and sixteen females. Therefore, our sample was twenty-three college students. This concluded that our sample was 30% male and 70% female.
NHST and the values it produces can help users with identifying a general pattern or transition to the use of more statistical methods that are more appropriate to their experiment. Individuals still seem to confuse what NHST is and what it is not. Many criticisms lie with its use in an unrelated sense, or in data where the values of the NHST do not further the argument or evidence of an experiment. It is important to remember that NHST can be used for certain situations, however, it cannot deviate and become a blanket statistical test for all data and
Methodology In my thesis I utilized the quantitative content analysis method. There are many definitions of this research method from different authors. Most of the definitions include similar principles. The research should be systematical, objective, quantitative and replicable.
The term Research Methodology refers to a set of procedures, methods & techniques that are put together by the researchers to obtain a solution to the problems they confront during the collection of data. The researchers look for the most crucial data which is inevitable for the research. Generally there are three kinds of approaches or research methods namely Qualitative, Quantitative and Mixed. These methods are used to gather data and resolve issues that emerge during the process of data gathering. The researcher can bring forward his findings either in the form of quantitative or qualitative or mixed research methodologies only when the data is collected based on the preliminary data gathering process and the secondary data gathering process.
The four most commonly strategies used in the quantitative research process are: observations, interviews, document analysis, and visual materials. By using these strategies, researchers are able to provide credibility and trustworthiness to their final product. However, with any form of research there are risk involved, strengths in using the chosen strategy, and advantages.
