Quantitative Research : Data Collection

Quantitative research is done to find the accurate facts by evaluating the problems like opinion, behaviour by using numerical data. This research is based on theories, hypothesis, collecting, analysing the data to make the research accurate.

The research topic is selected, the testable research question is developed, research on the topic is found, the literature review is completed, and a decision is made on the research design. Now, one of the most important steps in the research process to accomplish is the collection of data. Notwithstanding the research project and whether the method of research is whether qualitative or quantitative, data must be collected. Data collection is essential whether the method of choice is a mail survey, a telephone survey, an interview, an experiment, field research, or secondary data analysis. Data collection is an important aspect of any research study. Inaccurate data can impact the results of a study and ultimately lead to invalid results. During the data collection step, a significant amount of time, energy and attention are required. In order to ensure the data collection process is valid and successful, one should adhere to the four steps involved: (1) the construction of a collection data form which is used to organize all data that is collected; (2) the designation of the coding strategy used to represent data on a data collection form; (3) the collection of the actual data; and (4) entry into the data collection form (Salkind, 2012).

The researcher must set a clear hypothesis, showing the relationship between independent and dependent variables. In quantitative research tools are used to collect numerical data. The information can be gathered using questionnaires or some type of equipment. Quantitative data is efficient at testing a hypothesis, but can miss contextual detail. In quantitative research, the researcher is often objectively separated from the subject matter. One of the ways quantitative research is different from qualitative research is that quantitative research requires extraction of large amounts of statistical data. Qualitative research is focused in on personal viewpoints and opinions of a smaller number of subjects (typically). Qualitative research can take more time than quantitative research (McCusker & Gunaydin,

Quantitative research methods are objective as it uses measurements and analysis of statistical data to answer the study question. The researchers’ opinions do not affect the outcome of the study, ensuring that the study is unbiased. Another advantage is quantitative research uses numbers and statistics which is understood universally (Houser,2008).

The methodology was described with the data collection method. Quantitative and qualitative questionnaire which consisted of closed questions with a choice of fixed answers and free text to enhance qualitative data were sent out in the form of mailshot, followed by telephone call to non-respondents and it was repeated for more wider sample results to gain more evidence to reduce bias (Parahoo, 2006).

A quantitative study has objective stances, logic, and numbers focusing on unchanging data and details (Babbie, E.R., 2010). The aim of quantitative research is to classify features, count the features, and construct statistical models to explain what was observed (McNabb, D.E., 2008). It has eight characteristics:

In defining quantitative research the term can be dichotomized. Firstly, research refers to creative, systematic work with the intention to increase the knowledge of man and thereby devise new applications (OECD, 2002). In addition Gray (1997) stated that research should improve performance and that the results should be

This study used a quantitative methodology of data collecting to answer the research questions. The specific research questions studied included the following:

Quantitative analysis involves the techniques by which researchers translate data into a numerical form and subject it to statistical analyses (Lesson 6 2017). I would design a quantitative research project by focusing on measurement. I will provide numerical statistics in support of my research. Lets say I am researching on the growth of the MS-13 gang. I will present numerically the growth or declination of the member attendance, crime rates, gang activities, etc. Then, with all the results, I will be able to form a conclusion on whether the gang has or has not grown over the years.

Quantitative research: In quantitative researches, surveys are conducted to collect numerical data. Most of the surveys include close-ended questions which are less time consuming. It is quite easy to collect such data as consumers tend to be more co-operative. The collected data is further analyzed for a proper conclusion.

Quantitative research as described in slide 4 of the lecture handout translates data into number that can be studies mathematically. One example of this that I experience this in law enforcement is when measuring the effectiveness of enforcement operations. The numbers and type of enforcement actions being taken in certain area are compared against the number and types of crimes in those areas. For example, is an increase in the number of suspicious person stops resulting in a corresponding decrease in burglaries.

Quantitative research involves collecting data, which can be expressed numerically. The design is well structured with pre-determined outcomes. It frequently involves testing a hypothesis, which then can be analysed from the data deductively using statistical methods. Using numerical data is easier to analysis mathematical, so larger sample sizes can be utilised compared to qualitative research, therefore giving a better representative of the population; along with simplifying the process of making a generalisation. Another advantage is that studies can easily compare to similar findings (Kruger, 2003). The disadvantages are the results are limited and might not provide a proper understanding of the topic. Also, statistics and leading questions can be used to give a false representation of the data when summarising.

In general, there are several methods for data collection and the different data collection methods provided its own advantages and disadvantages (Sekaran 2003, p. 223). For carrying out the data collection, the appropriate methods should be applied. In the research, the data collection could be done through the interview, for example, face-to-face and telephone interview. To collect the data by using interview technique, the questionnaire is commonly employed as the instrument for gathering data, the questionnaire could be able to distribute by mail or electronic mail. In addition, the data collection could be conducted by observation of individuals with or without audio or video recording. Before choosing the methods for data collection the expertise of the researcher, the degree of accuracy required, time and resources must be taken into consideration. Thus,

This study will use quantitative methods of research. The major advantage of using quantitative research design is that it is an exceptional method for making conclusions and agreeing or disagreeing to any

Data Collection is a vital aspect of any type of research study. Erroneous data collection can impact the results of a study and ultimately lead to invalid results. Data collection methods for impact evaluation vary along a scale. At the one end of this scale are quantitative methods and at the other end of the scale are Qualitative methods for data collection. Choosing a particular data collection method will depend on the accuracy of information they will yield and the practical considerations, such as, the need for personnel, time, equipment and other facilities, in relation to what is available
