Quantitative research is a method to quantify data with a combination of deductive logic and empirical observations to define and identify what factors or variables in the population that influence an outcome. The data is collected by using structured data collection instruments such as content analysis, discourse analysis, questionnaires and surveys to produce a narrow-angle lens which is able to eliminate biasness. Quantitative research is an important research approach to test the hypotheses and statistical analysis is developed to support the hypotheses. (Park, 2012) It is often designs in closed-ended questions to gather and interpret the data from a large sample which will be the representative of the whole population.

Researchers will need to have a close involvement with the participants to understand their perspective and interpretation regarding on a situation or phenomenon to develop an in-depth explanation. Qualitative research is done in a wide-angle lens as subjectivity is critical to examines the breadth and depth of phenomena. It is often designs in open-ended questions in order to analyse and interpret the data. The method for qualitative research includes ethnography, interview, historical research, participant observation and textual analysis. (Brennen, 2013) With the strengths of the both qualitative research and quantitative research, triangulation research method will be conducted to enhance and validate the research.
Triangulation research is a term which refers to the integration of quantitative and qualitative data within a single study. (Park, 2012) The combination of two research methods leads to a greater validity to the paper as there are variation in data collection from different perspectives. Triangulation research is frequently used to have a comprehensive data and a better understanding of the quantitative results and qualitative findings. In this research paper, triangulation research is conducted by distributing surveys and conducting an in-depth interview.

It is a characteristic or attribute of an individual which can be observed or measured. (Creswell, 2014) Variables often employed in studies to measure attitudes or behaviour include gender, racism or social issues. There are two types of variables which are independent variables and dependent variables. According to Creswell (2014), independent variables will affect the dependent variables. Independent variables are also called as manipulate variables. It is to investigate the effect of a dependent variable. Dependent variables are the outcome that influenced by the changes in the independent variable. It is to measure the effect of the independent

Variables (example): Problem: Will the mass of an egg change after being soaked in distilled water or corn syrup for 24 hours? Variables: a) Independent (Manipulated) - what are we changing? The amount of liquid in the cup, with the egg is manipulated because we don’t have a lot of corn syrup.
The difference between dependent and independent variables is that the independent is the variables that are changing or controlled in an experiment to test the effects on the dependent variable. In the Stefan-Boltzmann law experiment, for example, volts would be the independent variable while the radiation in millivolts would be the dependent variable. 7. What are the differences between qualitative and quantitative
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
For instance, a study that defines the impact of poverty (X) over crime (Y) [poverty crime] discovers poverty as the independent variable while a study that seems at race (X) as a poverty predictor (Y) [race poverty] discovers poverty as a dependent
Introduction Qualitative research are those kind of researches that an outcome is obtained without the application of statistical methods of data analysis (Strauss and Corbin, 1990 cited in Golafshani, 2003). However, the qualitative research takes a direct approach, where the researchers arrive at a conclusion through the observation of events as they occur naturally without external interferences (Golafshani, 2003). Ethical and methodological issues may arise, therefore in order to demonstrate the legitimacy of Qualitative research it is important to integrate rigour and trustworthiness. Potential ethical issues There is the need to take into consideration ethical issues that may arise from conducting qualitative researches.
CHAPTER 5. INFORMATION & COMMUNICATION Quantitative v. Qualitative Studies Quantitative investigations are scientific, objective, and effective in describing phenomena in terms of magnitude (Balian, 1988). Quantitative investigations use numeric values and statistics to identify patterns, to objectively quantify relationships between variables, and to make predictions. In addition, because large sample sizes are used, data can be generalized to larger populations.
3. QUALITATIVE RESEARCH THEORY 3.1 QUALITATIVE RESEARCH Qualitative research is a form of research in which the researcher collects and interprets data, meaning the researcher is as important in the research process as the participants and the data they provide. Reason and Rowan (2004) have argued that the core element of a qualitative research approach is to connect meanings to the experiences of respondents and their lives. According to Clissett (2008) qualitative research involves a variety of research methods that can be used to explore human experience, perceptions, motivations and behaviours. Qualitative research is characterised by collection and analysis of words in the form of speech or writing.
“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
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.
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.
Mass vs Tangential Velocity K.Kirtanaa, Ms. Perez, November 14, 2016 Research Question: What is the effect of increasing mass on tangential velocity? Introduction: The experiment explores the relationship between the independent variable and the dependent variable. The independent variable is what you change in an experiment.
