Experimental Design College Essays Samples For Students

1.0 Abstract
Industrial and organization research is normally concerned with human mental processes and behavior in organizations and businesses. Organizational research normally uses the quantitative research method because most the problems that are studied meet the four objectives relevant to scientific understanding; description, explanation, control, and prediction. However, qualitative research is increasingly becoming relevant in Industrial and organization research. This creates the need to understand both qualitative and quantitative research techniques.

2.0 Introduction
Qualitative research is a research design that seeks to study research participants in their natural environment in an attempt to interpret phenomena or develop a theory. ...

Introduction

Experiments are designed to test the hypothesis. In an experimental design or design of experiment (DOE), participants are assigned to variable conditions in an experiment. Usually, experiments are designed in such a way that participants are divided into two groups, i.e. a control group and an experimental group, and then a change is introduced in the experimental group to determine the outcome. There are two important types of experimental design; True experiments and Quasi-experiments. Both types of experimental designs are used to check the cause of some particular phenomenon.

Types of each design

True Experiments
In a true experiment, subjects or participants are randomly assigned to ...

Experimental design for the nursing research proposal

This research uses quasi-experimental design. Quasi-experiments are studies that aim at evaluating interventions without using randomization. These experiments aim at establishing a connection between the intervention and outcome (Sullivan & Garland, 2010). The use of the quasi-experiment design is the most appropriate since the intervention often cannot be randomized in a hospital or public health setting. A quasi-experimental design offers an experimental design in which participants are not assigned randomly into different groups (Maltby, Williams, McGarry & Day, 2014). A quasi-experimental design is more frequently implemented than the randomized experiments.
Quasi-experimental designs are universal in the staffing levels of nursing staff aimed ...

The comparison of the attentiveness and performance of teenage boys and girls in school

Quasi-experimental design and the topic
The Quasi-Experimental research design is that method that can be used in the study of groups in the comparative approach. This methodology is tested on the basis of how it can be used to achieve the provided goals. It also limits the biasness that can be associated with the research. What makes this methodology to be better suited to the topic is that it is used to test the causal hypothesis (White & Sabarwal, 2014). It can therefore provide a better way of studying and understanding the topic.

Independent Variable and Dependent Variable

The current study seeks to assess the efficacy of PECS in the treating non-verbal individuals who suffer from autism. Specifically, the study seeks to compare effectiveness of PECS in promoting functional communication compared to the conventional methods for persons with autism. It also seeks to assess the conditions under which PECS is effective. Lastly, it seeks to compare the success rate of conversational speech between those who start using PEC at an early age and those who adopt at a later stage in life. Therefore, the independent variables are the educational program adopted (PECS and conventional teaching program), environmental ...

What is the relationship between the predicted outcome and the claim being tested in scientific experiment? An experimented outcome can be compromised in two ways. What are they and how do they differ?
The predicted outcome is a common aspect of science with a particular interest in scientific research studies. In science, questions about truth and the claims of certain phenomena are answered through empirical evidence. Nevertheless, there are instances where scientists make educated guesses on a particular test subject. A predicted outcome can be proved right based on measurable evidence in a hypothesis experiment. On the other hand, ...

Introduction

In my experiment, I used the sequential design as my experimental design. It guided me to agree with the hypothesis,” that emotionally loaded words like “sex” and “prostitute” must be exposed for a longer time to be perceived than neutral words. I conducted surveys so that I could come up with the findings and the conclusions of the experiment. The dependent variable in the experiment was the threshold in which the loaded words are used. The independent variable is the time taken in the surveys that I conducted.

The sequential experimental design requires the researcher to complete a ...

VTE Nursing Research

Venous Thromboembolism
Introduction
Venus thromboembolism (VTE) is a condition that includes both pulmonary embolism (PE) and deep vein thrombosis (DVT). DVT commonly occurs when blood clots in deep veins normally in the pelvic veins or in the legs. However, VTE is common any vein in the human body. Patients who develop VTE have a 35% to 65% chance of dying from it. It is important to research on Venus thromboembolism (VTE) because as the third most common cardiovascular disease, it is a leading cause of mortality and mobility worldwide. VTE results from slowing of the blood flow (stasis), damage of ...

An experimental design is a plan that guides information gathering where variations are present. The plan shows how the experimenter will present or withhold the experimental event. The experimental design is important when conducting experiments because it has a direct effect on the results arrived at in the end. An effective experimental design should be able to rule out alternative explanations of the findings. Experiments are conducted in environments where several factors exist that can affect the impact of the treatment on the subjects. The design should allow the experimenter to confidently attribute the behavior change to the presence or absence ...

Quantitative Article Critique

Where does this research fall under based on the intent of the researcher? Explain in depth
The study falls under the category of evaluation research. Evaluation research focuses on the processes and outcomes of attempted solutions. The current study is a pilot test aimed at evaluating the effectiveness of an asthma intervention program for school children “Okay with Asthma”. The research study was specifically aimed at evaluating the effectiveness of the program in improving the asthma knowledge and attitudes of children towards their own illness.

In the present day society, cases of racism being expressed openly have reduced, but there are chances that it is still perpetrated in subtle and non overt ways that are not clearly discernable. This is known as “modern racism.” Over the years, there have been fears that the justice system is not impervious to racism, and this has become a subject of interest for many scholars. A good example is Johnson et al (1995) who carried out a study to determine whether race affects decision making during criminal trials. Although the research was an eye-opener in several ways, a gap still exists ...

Introduction

The concept of validity was first originated by Stanley and Campbell in 1966 and later elaborated further by Campbell and Cook in 1979. The concept of validity has a significant impact on how researchers evaluate their work. Validity refers to the extent to which to which a given test measures that which it claims to measure. It is important to evaluate the validity of a test to ensure accurate interpretation and application of test results. There are four main types of validity; construct validity, statistical validity, external validity and internal validity. This paper seeks to compare and contrast the characteristics of external, ...

Introduction

A natural phenomenon is any non-artificial event not produced by human activity but may affect humans. Natural phenomenon includes weather, decay, erosion and volcanic eruptions. Most natural phenomena are termed harmless.
Erosion is the process which leads to the removal of material from a section of the earth. Erosion may occur when solids such as rocks are weathered and transported to another place by wind, water, and ice (Toy, Foster, & Renard, 2002). Although soil erosion is a natural process human land use such as deforestation, industrial agriculture and urban sprawl have profound effect on erosion. A certain amount of ...

A Critical Review of Program Evaluation Study: Family Life-Skill Program
Introduction
There is sufficient evidence suggesting that the Temporary Assistance to Needy Families (TANF) program in New Hampshire, USA is giving increased attention to women empowerment by introducing the Leadership for Employment, Achievement, and Purpose (LEAP) curriculum that involves a welfare-to-work process. The program evaluation authored by Wichroski et al. (2000) seeks to determine the impact of the program in relation to the program objectives and expected outcomes. On the other hand, this discussion will determine the adequacy of the evaluation by looking into the methodology and the areas ...

In this assignment, two studies were selected and evaluated on the basis of the appropriateness of their respective research designs. The first study was conducted by Coleman and colleagues (2013) to “examine the relationship between health-related quality of life in individuals with spinal cord injury and mental health of their caregivers in Columbia, South America.” On the other hand, the second study was conducted by Richey and Hodges (1992) to determine the effectiveness of respite care in reducing caregiver burden. In the study by Coleman and colleagues (2013), a descriptive design was used. This design is appropriate for this ...

Abstract

The world in which we live is surrounded by a number of forces that may each act independently or jointly to keep nature in a state of equilibrium. A force is defined as either a push or a pull whose resultant effect may be either translational, or distortional (Andy, 2002). In this practical experimental undertaking, we investigate the distortional effect of force on objects.
The main aim of this experiment is to prove the celebrated scientific law; Hooke’s Law. Aside from ascertaining the validity of the aforementioned principle, we proceed further to determine the spring constant of the spring used in ...
