Social science and impact in early marriages in higher education settings.

Higher learning institutions have for a long time been associated with early marriages. Most youths get engaged to early sexual relationships leading to unwanted pregnancies and sexual transmitted diseases. In an attempt to cope with the results, the youths get married with limited financial sources to support these marriages.
More interactive results with most of these students associate the contents of the syllabuses in these institutions to this behavior. The students think that social science is too exploitative on affairs and social settings and these makes the youths believe that marriage at early ages can work. The following is a ...

Question 1

Descriptive research purposes to describe the characteristics of a given population or a phenomenon that is of interest to a researcher. It is also referred to as statistical research. Descriptive research is systematic, factual and accurate. In descriptive research, the researcher does not evaluate causal relationships between variables. Therefore, the internal validity requirement for this kind of research is low. Descriptive research relies on measures of central tendency and dispersion, frequency distribution and graphs. On the other hand, inferential research aims at making predictions about a given population from a sample that the researcher analysed. In inferential research, the researcher evaluates causal relationships and ...

A correlational study is meant to determine whether two variables are linked. During a correlational study, an increase or decrease of a variable is examined to determine whether it increases or decreases the other variable (Kalla, 2011). To examine the relationship between academic performance and the levels of loudness of music using correlation, would require the selection of a group of students, say from the tenth grade. These students would be split into four groups and placed in a controlled environment where the first group would listen to no music, the second group would listen to low music, the ...

Research Methodology and Design

Introduction
Research method and Design is meant to provide more information on how the study of the research question will be conducted in order to achieve the stated research objectives. It entails gathering data, instrumentation, compilation, and analysis among other aspects that will ensure collection of objective, relevant and accurate facts . Several academic scholars and researchers have conducted predictive and descriptive studies with an aim of validating the true nature of various aspects of transformational change that is necessary in transforming both community and for-profit colleges in to enhance the quality of education. This study will build on ...

Introduction

In the research on disaster management during a disastrous situation both natural and man-made disasters such as earthquakes, hurricane, tornadoes and terrorist attacks, I would suggest to use Descriptive Design. These kind of design provides answers to the questions of where, when, what, who and how. It provides information concerning the existing status of the happening and explains what exists with respect to the condition of the situation (Creswell & Creswell, 2007). It involves collecting data in order to test hypotheses or answer questions concerning the current status of the situation. It also involves conversion of data in numerical form so ...

Part 1:

1. Calculate the sample size needed given these factors:

The factors given for calculating the sample size are as follows:

one-tailed t-test with two independent groups of equal size
small effect size = 0.2
alpha = 0.05
beta = 0.2
Power = 1 – beta = 1 – 0.2 = 0.8

Using the priori function:

Using the priori function on GPower, the sample size based on the factors above was determined. The results of the analysis are as shown below.

Results:

t tests - Means: Difference between two independent means (two groups)

Analysis: A priori: Compute required sample size

Input: Tail(s) = One
Effect size d = 0.2
α err prob = 0.05
Power (1-β err prob) = 0.8
Allocation ratio N2/N1 = 1
Output: Noncentrality parameter δ = 2.4899799
Critical t = 1.6473230
Df = 618

Quasi-experiments are research designs that attempt to mimic an experimental design. However, the researcher cannot control the assignment of study participants to groups: a key feature for true experiments (Wadsworth, n.d.). This paper explores quasi-experiments as a research design.

Part 1

Advantages of Quasi-experiments
Firstly, quasi-experiments, as the name suggests, are not true experiments. They contain elements of both a true experimental and correlational research (Jackson, 2012). Therefore, they allow the researcher to obtain stronger conclusion compared to when they conduct a pure correlational research. Secondly, quasi-experiments are useful in circumstances when conducting a true experiment is either infeasible or very ...

Explain the difference between multiple independent variables and multiple levels of independent variables. Which is better?

It is important to note that design experiment requires researchers to decide on the type of dependent variable that they should use in their respective study and distinguish the same from the independent variables. However, every research ought to have a single dependent variable, but the independent variables can be many, an aspect that makes the independent variables be considered as parameters. Therefore, for our case, multiple independent variables indicate the use of many parameters in conducting a study. For example, if we take a survey to find the extent of obesity in a given area, and take the ...

The progress of learners with disabilities is monitored in order to identify the fitting instructions as well as those that need modifications. Essentially, the standards set to provide sufficient and effective instructions within the curriculum are followed to facilitate changes in accordance with the recommendations from instructors. The reports of students’ success in meeting the course requirements are assessed by professional staff who inform about the necessarily changes essential for facilitating learning. A decisive evaluation of student progress ought to be conducted by displaying evidence from standard tests, observation, and informal checkups among others. The evaluation determines the problems ...

Psychology

The independent variable identified for the study include the individuals who score high on MMPI and the dependant variable identified for the study is the reporting of instances of social injustices. The first hypothesis will be tested out using regression analysis. The independent t-test will measure the difference between MMPI scores of both groups and also determine the difference in the number of social injustice cases. The scale of measurement used is nominal because the data is easily differentiated. Nominal measurement is done through a YES/ NO and a likert scale. Numbers are assigned to the nominal items to gather the ...

Single subject research has always posed some significant challenges to researcher s and scientists working in the field of experimental psychology. The fact remains that unlike popular opinion, single subject research can have statistical validity and can provide the necessary tools to provide usable data during many experiments(Kratochwill, 1978). Horner et al., (2005) provided some useful insights on how to assess the quality of a single subject research paper.

Abstract

The paper is devoted to the elaboration of token economy system for students, who prefer being absent at classes. The reasons of absence were considered, and appropriate tokens were suggested. The class of juniors, who studied Microeconomics, was taken for conducting an experiment with tokens in the form of additional marks. These marks gave an opportunity at the end of the course to choose the exam questions personally based on their complexity and quantity, namely to create an examination card, and an opportunity to decide how to pass an exam, namely completion of the test, oral discussion, presentation preparation ...

Introduction

Research Topic
Eating chocolate has been associated for a long time with silhouette and weight problems, but recent research indicate that consuming chocolate can improve memory. Based on Jones and Wilson’s (2011) study, who found that eating chocolate two hours before taking math tests significantly improves scores, this report aims to investigate whether this information is valid, and if so, how does it relate with men versus women population.

Research Question

What is the effect of eating chocolate upon memory?
Hypothesis
Based on the previous research that found that women are better than men on memory tests after ...

Abstract

The main aim of this paper is to analyze, evaluate and postulate the results of an in-class experiment that was carried out to test the relationship between the intentions of ostracism and people in extreme groups. 73 participants aged between 19 to 25 years took part in the survey that involved completing a series of vignettes and manipulation checks on a hypothetical individual, ‘Mason’ and his perceived involvement in extreme groups. The 2 x 2 between-subjects factorial experimental design was used for the research. The results indicated high intentions to ostracize Mason due to his involvement in an extreme group. From ...

1.0 Pivotal response therapy (PRT)
Pivotal response therapy/treatment/training is one of the early behavioral intervention techniques developed for management of autism. This techniques is built on the premise that autism interferes with “pivotal behaviors” that ultimately underlie other behaviors are deficient in autistic children. The pivotal behaviors/areas are initiating activities, motivation, self-management, feelings and responding to multiple/complicated cues (signals). PRT therefore aims at increasing pivotal behaviors, particularly motivation, which would in turn enhance generalization. The autistic child chooses the activity and is rewarded (positive reinforcement) for every correct responses or attempt. As such, PRT trains the child to ...

Hygiene refers to the practices that communities perceive as upholding or preserving healthy living, while an infection is an attack of parasites on a host organism. Hospitals being public places where both sick and healthy people mingle are likely to be more vulnerable to infections compared to other places. The sources of infections in hospitals include hospital staff, patients and the inanimate environment.

Maintenance of hand hygiene is one of the simplest yet most effective methods in prevention of infections. In spite of the society emphasizing on the importance of hand hygiene, many people including health care personnel, do not ...

Experimental design chosen

The aim of the research proposal is to investigate the impacts of various hand hygiene techniques on transient flora and consequently, overall hospital hygiene and the reduction of infections in the hospital. A quasi experimental technique based on a randomized block design shall be chosen. The blocks shall be based on the techniques of hand hygiene and their impacts on transient responsible for infections. Therefore the blocks shall be; (1) social hand washing, (2) careful hand washing, (3) hygienic hand disinfection and lastly surgical hand disinfection. An equal number of persons practising each of the techniques shall be selected.
