Quantitative “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).
Methodology The method used for the study was quantitative, this was chosen rather than a qualitative as this deals with facts and figures and is an investigatory type of study. This can be either experimental or non experiment. Experimental is the method used in this study which looks at cause and effect, and involves dependent and independent variables. (Balnaves and Caputi, 2001) A qualitative study can be described as interpretive which deals with personal thoughts and feelings (Flick, 2009).
The researchers included both a hypothesis and research questions. They stated a hypothesis, however it is a research hypothesis versus a null hypothesis. A research hypothesis explains there is correlation between two or more variables. A null hypothesis is a classification of hypotheses that states there is no connection between the independent and dependent variables. Statistical testing is performed to determine whether the statement is acceptable or not. Whereas the research question is an analysis statement detailing the variables and population of the specified research study (Adams, 2015). The hypothesis, the authors were hoping to prove, was whether the use of music would reduce pain and anxiety in postoperative pain in a particular patient population during a defined time frame (Allred et al., 2010). An example of a null hypothesis for this study would state music would have no effect on postoperative pain in a particular patient population during a defined time frame. There were four research questions the researchers attempted to answer. Three of the four questioned the effect of music on the patient’s pain, anxiety, and physiologic parameters. However the fourth question pertained to the impact of music on the amount of opioids taken from the beginning of the intervention until six hours later (Allred et al., 2010). The clinicians had not mentioned this component of the study before
When discussing the research question and hypothesis, one might interrelate these two concepts when in fact these terms differ from one another. The research question guides the research by creating a question that pertains to a particular topic one might be interested in gaining more knowledge in that particular area (L. Sabol, personal communication, April, 2016). Research questions can come from values, theories, or previous research (L. Sabol, personal communication, April, 2016). The research question within the article that the researcher wanted to examine is, “To what extent do pre-college characteristics and the academic performance of Black male student-athletes differ from their student-athlete peers?”(Horton, 2015, p. 289). With this research question the author Horton (2015), is attempting to figure out whether there is a relationship between Black male college student
The purpose of this essay is to apply critical thinking and awareness by comparing and contrasting two chosen fields of practice being mental health and rural and remote practice. This paper will discuss a brief historical outline in regards to both fields, together with a statistical overview of certain challenges and concerns that occur within the field of mental health and rural and remote practice. An emphasis will placed on the challenges faced by the client, while comparing and contrasting issues such as social disadvantage, infrastructure, drugs and alcohol misuse. Likewise, challenges faced by the worker and a comparison of the interventions used in both fields, along with the diversity of the two working environments and the
Research Article Analysis CJA-334 November 7, 2011 Research Article Analysis The purpose of this essay is to analyze a research peer-reviewed article in criminal justice. In this case, I chose to analyze the research conducted by Hurst, McDermott, and Thomas (2005) titled, “The attitudes of girls toward the
Qualitative Meta-Analysis Intervention study Quantitative Mixed Methods Case study Longitudinal Observational Cross-sectional This study is quantitative because it looks at a large group of people based on scale based on observed indicators. It is also observational because, as I previously stated the scale is based on observed indicators, and looks at independent and dependent variables. Lastly, this study is also longitudinal because, it repeatedly observed the independent variables over time.
Running Head: CRITICAL ANALYSIS OF A QUANTITATIVE STUDY Critical Analysis of a Quantitative Study Introduction A critical analysis of a research involves a strategy to evaluate the components of a research study and determines the strengths and weakness associated with a research. Objective of this research is to prepare a
Hypothesis is typically used in quantitative research only. Moreover, when a question poses an inquiry on the relationship between two variables, a hypothesis is a statement declarative in nature of the relationship between different variables (Pajares 2007). A researcher chooses whether to use a question or a hypothesis depending on the purpose of the research, its objectives, the methodology for the research and the preference of the audience to receive the research. A researcher must be able to interpret the final outcome with reference to the research questions or the hypothesis used (Pajares 2007). A research requires a minimum of two hypotheses namely a null and an alternative hypothesis.
The research method followed in this study is an experiment because there are two variables identified as dependent and independent variables. Also, the experimenters assigned participants randomly
Is this a quantitative or qualitative study? Explain your choice. This study quantitative, because it shows numbers and data to show how many injuries have been done to nurses during the restraining of aggressive patients and the factors that can be modifies to improve the nurses during the restraining.
Research methods are put to the test with the help of an experiment. An experiment is composes of a manipulation with an independent variable and an unplanned task of conditions to a contributor. Using both of these components confirms a strong experiment. The independent variable, is well known as, the changing
Positivists So, they are associated with the mixed methods approach. Research methodologies can be divided into three different approaches; quantitative, qualitative and mixed methods. 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.

On the other hand, investigate the effects of how the independent variables affect the dependent variable. In addition, this chapter also includes a proposed conceptual framework, theoretical models and hypothesis development. 2.1 Review of the Literature 2.1.1 Dependent
