1. Explain Cause and effect and Causation in relation to the various research methods (experiment, correlational, and qualitative) discussed in lectures and readings from the textbook and articles. That is, what is the best way to establish cause and effect?
Experimental research attempts to identify relationship by conducting controlled experiments psychological experiments; furthermore, the experimental is a quantitative approach designed to discover the effects of presumed causes (Christensen, Johnson, & Turner, 2014). The key feature of this approach is that one thing is deliberately varied to see what happens to something else to determine the effects of presumed cause. Some individuals use exercise to see if they can lose weight,

This definition has three primary components that are essential to understanding the nature of qualitative research. The first component is that qualitative is interpretive. Qualitative data consists of words, pictures, clothing, documents, or other non-numerical information. During and after the data is collected, the research continually attempts to understand the data from the participant’s subjective perspective. The most important task of the qualitative researcher is to understand the insiders view then the researcher takes of objective outsider and relates the interpretive subjective data to the research purpose and research questions. In qualitative research, the research questions are allowed to evolve, or possibly change during the study because qualitative research is usually focused on exploring phenomena; consequently, quantitative typically does not allow the change of that sort because the focus is on hypothesis testing. Qualitative is useful for understanding and describing local situations in theory and for theory generation; in contrast, quantitative research tends to be more useful for hypothesized testing. The second component of qualitative research is multimethod. This means that a variety of methods are used to collect data. Data collecting methods include the personal experience, introspective analysis, and individual’s life story, interview with individuals, written document, photographs and historical information. Qualitative research uses several of these data collecting methods to try and get the best description of an event for the meaning it has for the individuals being studied. The use of several methods is referred to as triangulation because it is believed that the use of several methods provides a better understanding of the phenomena being
Identify the hypothesis (testable question) that the study was trying to answer and describe the methods of research used in each study.
Experimental research is the one type of research that allows psychologists to make causal statements. It is where the researcher changes one or more variables that may have an effect on some other variables (King, 2016). The hypothesis is a specific expectation about what is going to happen in the experiment (King, 2016). In the research, the hypothesis was that women would perceive fat talk to be more socially acceptable than men (Katrevich et al., 2014). The other elements of experimental method are dependent and independent variables. The independent variable (IV) is the cause of the results, and it is changed by the experimenter to find the effects, but the dependent vari...
The term methodology refers to the way in which we approach problems and try to find answers and in social science, it applies to how research is conducted, our assumptions, interest and purposes shape which methodology we choose (Steven, 2016:3).Qualitative research is understanding people from their own perspectives, their viewpoint and experiencing reality as they experience it. Qualitative research has many approaches or methods of collecting data and one of them is an interview which I have chosen to explain further based on it as a method of collecting data. The interview is the most common method of data gathering used in qualitative research and it is used in deferent ways by every main theoretical and methodological approach.
Qualitative research is an approach that attempts to situate an activity that locates the observer in the world by providing the study to occur in their natural setting and by attempting to make sense of, or interpret information (Denzin and Lincoln, 2005). A characteristic of qualitative research is to use a variety of empirical materials such as personal experience, interviews, and questionnaires. It is imperative to understand the task at hand and how to fully carry out the study when using a qualitative research approach in order to find out the information needed. One view of qualitative research is it involves examining individual’s experiences and documenting those experiences in detail (Jones, 2011). By documenting these observations the researcher is ensuring validity in his or her data and giving the correct creditability to those who participated in the study.
Research allows for the undertaking of information-finding activities; establishing facts and reaching new conclusions. (Smith, M. 2010) It is important when conducting research to ensure to use the correct research design that will prove to be the most effective for the desired study being investigated. There are a number of different research designs; experimental, correlational, survey, observational, case study and ethnography.
The pie chart is an example of the promotions the research suggests as well as how much focus needs to be put on each of them.
In the criminal justice system it is imperative to understand why crime occurs in order to prevent them from happening. Researchers look for the cause of crime and experimental research is considered the best when determining cause and effect relationships. However, causality can never actually be proven only be hypothesized to a certain degree. Experimental research is used a top standard for the evaluation of other research methods as they are able to control the validity of the research both internal and external. Internal validity is the accuracy within the study itself while external validity is the ability to say the outcome is applicable to other groups. There are three main types of experimental research designs classical
A laboratory experiment is a research method that can be defined as an experiment that is conducted in a controlled environment. This enables the researcher to control factors that may or may not affect the results of the experiment in an uncontrolled environment. This type of research method is common due to the allowance of alterations to particular sections of their experiment in order to determine what and how their aim is either correct or incorrect. From this they can determine the cause and effect. Cause and effect is the acknowledgment of a relationship between events, or in this case, between results.
In scientific research, quantitative methods are used in order to provide empirical data for the investigation of various phenomena. In their article, Cruz et al., (2016) use quantitative research to identify the specific variables that apply to the occurrence of hypertensive disorders of pregnancy. This paper analyzes the research qualities of the article, noting that it fails to live up to the standards expected of quantitative research.
This essay intends to compare and contrast the strengths and weaknesses of the quantitative and qualitative approaches to research which addresses young people and bullying using two journal articles. The first article (quantitative) aims to “establish the relationship between recurrent peer victimisation and the onset of reported symptoms of anxiety or depression in the early teen years” (Bond et al. 2001, p. 480) while the second article (qualitative) aims to “investigate the nature of teenage girls’ indirect aggression” (Owens et al. 2000, p. 70).The two articles will be critically compared in terms of research design, methods used, approach to data analysis, reported results and the plausibility and appropriateness of the conclusions and recommendations posed. The aim of this essay is thus to evaluate and assess the methods of social science research currently undertaken in published research.
In public health, it is important to know how to evaluate the appropriate research methods that best addresses an issue and establish rapport with target communities or populations. To gain knowledge of this, a vignette on a community health clinic and the barriers keeping minorities from seeking healthcare services will be assess. This discussion will allow public health scholars to evaluate an appropriate qualitative research method to address questions raised in the given vignette and determine how they would establish rapport with a target community or population in order to effectively apply the appropriated research method.
sometimes referred to as causal-comparative research, which researchers use to explore possible cause and effect relationships (Mertler & Charles, 2008).
Prior to beginning the study, permission will need to be obtained from the institutional review board (IRB) and approval from the desired institution the study will take place (Creswell, 2014). Once the study is approved by IRB and the institution permits the study, then the study may begin. The proposed study will conduct interviews, observe classrooms, and collect narrative stories on underrepresented students in STEM who are in a wide range of class sizes and teaching styles. There will be three sets of interviews: before, during, and after the course. The observations and narrative stories will take place throughout the course.
The purpose of this research is to determine if there is a link between supplemental media from Khan Academy and student academic performance. Furthermore, the research also seeks to determine the attitudes of teachers and students towards toward Khan Academy, particularly during the intervention period. The results are parsed and analyzed with the intention of providing clear conclusions as well as reasonable answers to research questions. First, the general findings of the data will be presented. These will be general conclusions derived from detailed analysis of the quantitative and qualitative data. The detailed analysis of the quantitative data is presented in terms of increasing complexity beginning with averages
Research can be defined as an attempt to discover something (Wimmer and Dominick, 2014). Research design is about the methodology that will be used for the research. Hence, this section will be discussing about the method that is going to be used for this research that is qualitative method research. Qualitative research is also described as an unfolding model that occurs in a natural setting that enables the researcher to develop a level of detail from high involvement in the actual experiences (Carrie Williams, 2007).
