Types of Experimental Research Methodologies

There are two major approaches used in the nursing research which are qualitative and quantitative methods. However, we can use both plans to do the nursing research. If both methods used in the nursing research, it will be called the mixed approach. The qualitative analysis is the method where researchers use the process of inquiry and look answers how and why a phenomenon occurs in a situation. The examples of the qualitative approach are phenomenology, grounded theory ethnography, and qualitative

According to Yin (2003), there are two types of research approach. This includes quantitative research approach and qualitative research approach. A quantitative research emphasizes on transforming the data to numbers, quantities and statistics to formulate facts and to uncover patterns in a research. It addresses research purposes through empirical analysis that involve numerical measurement, the relationship between variables and analysis approaches (Zikmund et al., 2010). The sample size being investigated is typically large (Anderson, 2006). Quantitative research mainly uses questionnaires, surveys and other equipment to collect numerical or measurable data (Anderson, 2006). On the other hand, a qualitative research typically emphasizes words more than numbers

The first method the textbook brings up is surveys. The textbook describes this method as being a way to reach a larger number participants, and is used to see patterns and relationships among

Data collection methods are the third process.  Data can be collected in many ways such as: observation, surveys, focus groups, and reanalysis of existing data, questionnaires, and interviews (Hagan, 2010, p. 19).  Data collection is a vital portion of any kind of research.  Inaccurate data collection will affect the results of a study and inevitably lead to invalid results.

There are a number of methods of collecting data, some of them are – questionnaire, surveys, checklists, interviews, observations, focus group etc (Cordray, 1986; Einhorn and Hogarth, 1986).

Naturalistic Observation – observing people in their natural setting. The advantages to his method are; realistic natural behaviours, low demand characteristics, can generate new ideas for research and test existing findings. However the disadvantages are; lack of control of variables, observer bias, limited to public places or certain types of behaviours, which may create ethical issues.

Starting from the point of where a question has been posed, the researcher will need to develop a methodology; this will explain what the research question is and what methods will be used in order to answer the question. Mukherji and Albon (2010), state that the methodology will provide an explanation defining the intended process. They also explain that it is the ‘theoretical framework’ known as a paradigm that underpins the methodology (Mukherji and Albon, 2010:11). Methods are the approaches researchers use to collate data in order to answer their question. Methods can provide quantitative data, Mac Naughton et al (2010:59) describes this as producing ‘facts and figures’, or numerical data whereas qualitative data is more in-depth

The researcher will look at different methods and decide which should use to gather the information required to answer the hypothesis questions. These methods may both include quantitative and qualitative approach such as interviews, questionnaires, conducting experiments or gathering data through statistic. After choosing appropriate methods, the researcher will investigate possible ethical implications, validity and reliability of the data collected.

The survey method is commonly used in correlation and descriptive studies. A survey is less in depth than the case study. Surveys ask people to tell about their own opinions or behavior. When asking questions one must be careful of how the question is worded, this can be known as wording effects.

“Researchers who use quantitative research method seek objectivity through testable hypotheses and carefully designed studies, and gather date that can be reported in numbers and statistics” (Crawford, 2016, p. 66). According to Crawford (2016, p. 66) “conclusions from this study are drawn from statistics and generalized to populations of interest”. Unlike qualitative that helps to eliminate opinions and thoughts, quantitative quantify opinions and thoughts and they obtain results from a larger sampling population. As I had previously stated on my discussion board “Quantitative researcher’s collection methods include many different kinds of surveys for example; online surveys, paper surveys, online polls, face-to-face interviews, telephone interviews, and etc”(myself). “They use the surveys to measure attitudes, behaviors, and opinions” (myself).

For examples lets say we want to study the behavior between mangers and employees. Naturalistic observation would allow us to study them in there natural environment opposed to taking them to a different location that may change their behavior. If we were to take the managers and employees to a lab or another location it would not be their natural environment. If we want to see how they interact at work we must observe them at work.

When planning a sociological study it is not easy to determine the most effective way to evaluate the situation. With this study we determined that surveys and factual representations of homelessness would be most effective for our quantitative research. Quantitative research is defined as, “The use of sampling techniques (such as

In survey method research, participants answer questions administered through interviews or questionnaires. After participants answer the questions, researchers describe the responses given. In order for the survey to be both reliable and valid it is important that the questions are constructed properly. Questions should be written so they are clear and easy to comprehend.

Quantitative methods are those in which data are collected and subsequently analysed through a process sometimes mockingly referred to as ‘bean-counting’ (Daymon 2002). Normally this is kind of method use for surveys with questionnaires.

The data collection methods of the research objectives are containing both qualitative and quantitative. Most of it are
