Experimental design employs comparison as its strategy for the given research. It uses two groups, which the researcher uses for comparison purposes. These include the experimental group and a control group. The two groups used in a study have similarities, but the experimental group uses the independent variable, whereas the researcher the control group is not assignment of subjects to either control or experimental group because it is central to chance. Nevertheless, the researcher assigns cases to the two groups randomly. In order to determine the influence of the independent variable, investigators will measure the dependent variable, designated as scores, two times from both groups (Frankfort-Nachmias and Nachmias, 2008).
In addition, researchers take a single measurement, the pretest, for all cases before introducing the independent variable in the experimental group. Moreover, they also take a second measurement, the posttest, for both cases after exposing the experimental group to the independent variable.….

Experimentation is one of the common methods used in quantitative research. Premised on the positivist philosophy, an experiment is essentially conducted to investigate causal relationships between variables (Bryman, 2008). Indeed, this is one of the major strengths of experimental research compared to other types of studies -- it not only describes association between variables, but also explains causation between variables (Kothari, 2004). This essay describes the various components of an experimental method plan. The paper also explains threats to validity as well as nuances involved in interpreting results from an empirical study.
An experimental design has four major components: participants, materials, procedures, and measures (Creswell, 2014). Participants denote the subjects from which the required data will be obtained. The participants section should describe the process of selecting and assigning the participants. This involves explaining whether random or non-random procedures will be used to select participants, whether the participants will be randomly….

• What suggestions can you make for future studies of the DARE program?

The aims of DARE are long-term in nature, namely to encourage students to not abuse drugs over the course of their lifetimes. The only way to test this aim is to conduct a longitudinal study of a representative body of DARE graduates over at least a twenty-year period, to see if the intervention had a lasting effect upon their drug use habits. The control groups would be a group of students from similar demographics and geographical locations who did not have DARE or any other anti-drug program in their schools and a group of students who experienced an anti-drug education intervention substantially different than DARE. The selection of students would have to be balanced in terms of factors such as race, gender, and neighborhood, given that graduates of DARE programs might….

goal of the research is to conduct an assessment of probable issues relating to hiring a deputy director for the organization, which has operated without an actual office manager for a year. Consequently, the research objective is to identify positive qualities that an individual must possess to be considered for the vacant position of an office manager. In light of the current situation, acquiring a manager with positive qualities is the objective for the study because of the need to lessen the negative results of change in management and promote employees' receptiveness of the new manager.
Experimental Design

This study will entail conducting an experiment, which involves manipulating at least one independent variable and observing the impact on certain results i.e. dependent variable. The experiment will be conducted in the field because the study involves human subjects. Given these considerations, the most suitable experimental design is true experiment, which entails random….

Confidence in the criminal justice system, by David Indermaur and Lynne oberts

Indermaur and oberts (2009) commence by arguing the importance of the judicial system within any country, especially a developed one, where there is ongoing pressure to improve the quality of the criminal justice system. Throughout the past recent years then, various efforts have been made across the countries to reform and modernize the criminal justice system. The two authors as such strive to analyze these efforts and conclude on their effectiveness, based on the analysis of the confidence revealed by the people in the criminal justice system. In this examination, emphasis is placed on the reforms implemented in the UK and the confidence of the people in the criminal justice….

Ball-And-Sock Experiment
he Experimental Design

I altered the experiment slightly to help make sure that it would demonstrate the issues it was supposed to demonstrate without adding extraneous variables. Specifically, I was concerned that if I walked around all day with a sock on my hand, every person who interacted with me would ask about my sock and that would get in the way of the main point of simply forcing me to not to rely on my dominant hand in my daily routine. Likewise, there seemed to be no point to introducing the variable of self-consciousness since left-handed people don't usually wall around self-conscious and worried what everybody else thinks about their being left-handed. So, I simply wrapped the fingers of my right hand in some first-aid gauze to make it impossible to use them and then I wrapped an Ace bandage around my hand and wrist so that in….

limiting a researcher's view of the problem are situational factors that can skew the results of her experiment, i.e., effects of pretesting, social threats, and group differences (Trochim, 2008, 188). External factors, such as possible sample size, can limit even the type of testing available to the researcher. As such, researchers have come up with a number of different types of designs over the years. This essay will compare and contrast two of these; experimental and quasi-experimental designs.
"Experimental designs are often touted as the most rigorous of all research designs" (Trochim, 2008, 186). hat is so rigorous about them is that they are the strongest type of design in regards to their internal validity (Trochim, 2008, 186). This is because the basic form of the experimental design uses random assignment, or chance to group participants. In effect, this makes the two groups, if selected from the same sample, basically….

Threats to Validity in a Quasi-Experimental Design
Evaluating design choice: Walk Texas!

The research study by Bartholomew (et al. 2008) entitled "Walk Texas! 5-A-Day intervention for women, infant, and children (WIC) clients: A quasi-experimental study" is defined as quasi-experimental because it lacks a formal control group. The purpose of the study was to determine an intervention designed to improve the eating habits of low-income WIC clients. The participants were "primarily native Spanish speaking, Hispanic women, of low educational level" (Bartholomew 2008: 297). The study "utilized a pre-test post-test quasi-experimental design, with two intervention and two comparison clinics that were matched for size and ethnicity" (Bartholomew 2008: 297). The comparison clinics served as an informal control although participation in the experimental and control groups was not randomized, as would be the case in a true experimental study.

The purpose of the experiment was to see if low-income women who make use of the….

Quasi-Experimental Design on the Effect of TV Adverts on Children
This study carries out the evaluation of a research titled "A quasi-experiment assessing the effectiveness of TV advertising directed to children" (Goldberg, 1990 p 445). The paper examines the extent the research hypotheses have been able to address the study. The paper also examines the research dependent variables and independent variables. Moreover, the study investigates the extent the author has adhered to both external and internal validity for the research.

esearch question the study Addresses

Goldberg, (1990) carries out the experimental research to investigate the potential impact of television advertising on children. Although, the author does not provide the research questions, nevertheless, the author tests two hypotheses using the quasi-experiment to assess the effectiveness of television advertising that has been directed to children.

The efficacy of female condom skills training in HIV risk reduction among women

andomized clinical trials are often considered the 'gold standard' of good medical research. This is because randomized trials make use of an experimental and control group and the randomization process is designed to eliminate possible selection bias, which causes correlative rather than correlative factors to potentially skew results. In the case of Choi (et al. 2008) according to the study "The efficacy of female condom skills training in HIV risk reduction among women" a "randomized trial….

Experimental esearch Methods in Business
Experimental esearch Methods

The author provides a survey of the literature illustrating applied experimental research methods in cross-sections of business and organization types. The advantages and disadvantages of the experimental research methods are discussed for each of the examples provided which run the gamut from depression-era agricultural economics to research conducted for the National Science Institute. While the article focuses on business research methods, the range of examples from multiple disciplines serves to demonstrate the adaptability of various methods to distinct contexts, the importance of thoughtfully developed research questions, and perceptions in the field regarding scientific rigor. The article is intended to guide students in their exploration of the breadth and depth of experimental research methods and to convey a sense of the challenges of applied scientific inquiry.

(3) the extent of control required over behavioral events in the research context (Yin 1994; as cited in Naslund, 2005); and (4) the researcher's philosophical stance, i.e., his/her understanding of the nature of social reality and how knowledge of that reality can be gained. (Naslund, 2005)

Naslund (2005) states that qualitative research methods "primarily create meanings and explanations to research phenomena" and include data collection methods such as:

(1) Observation;

(2) Fieldwork including interviews and questionnaires, diary methods, documents and texts, case studies; and (3) the researcher's impressions and reactions to observed phenomena. Quantitative research methods serve to make provision of a broad range of situations as well as being fast and economical.

Commonly utilized quantitative research methods include those of:

(1) Laboratory experiments;

(2) Formal methods; and (3) Numerical methods and techniques. (Naslund, 2005)

Naslund states that analysis identifies a number of interesting trends and trends that….

Experimental Research
An experiment is a form of quantitative research that tests causal relationships. The researcher manipulates and controls the conditions under which individuals are observed to behave. Experimental research starts with a hypothesis and then modifies something in a particular relationship. The researcher has control over the environment, variables and individuals under study. At the end of the experiment, the outcome is compared with the situation before the modification. An experiment consists of a number of components:

Treatment or independent variable

Dependent variable

Pre-test

Post-test

Experimental group

Control group

Random assignment

Classical Experimental, Pre-Experimental, Quasi-Experimental and the Solomon Four-Group designs all differ in how they treat these components, thus impacting the reliability and validity of the experiment.

Classical Experimental Design comprises random assignment of cases to groups, a pre-test and a post-test, an experimental group and a control group. Each group is exposed to different conditions or stimulus materials. Random assignment is used to increase the likelihood that each….

1. The two theoretical perspectives behind research are the positivist perspective and the interpretivist perspective.

- Positivist perspective: This perspective focuses on the idea that knowledge can be gained through objective observation and measurement. Positivists believe that there is an objective reality that can be studied and understood through empirical evidence and scientific methods.

- Interpretivist perspective: This perspective emphasizes the importance of understanding the subjective meanings and interpretations that individuals attach to their experiences. Interpretivists believe that reality is socially constructed and that individuals' interpretations of the world are shaped by their unique perspectives, beliefs, and values.
