Introduction

The double-blind randomized controlled trial is an experimental procedure where neither the experiments subject nor the person conducting it has any information about the unique aspects of the experiment.
A double blind randomized controlled trial aims at measuring and comparing the outcomes that presents themselves from two or more clinical interventions. A single intervention will serve as a standard to compare or as the control in the experiment. The involved participants in the experiment will receive interventions in an organized random manner so that they all have the characteristics which are similar at every start of comparing them. Randomization ...

Introduction

Psychology refers to a scholarly and applied subject that entails the scientific learning of rational roles and behaviors. It is of great concern to note that gender biases have continued to dominate most aspects of psychological research. Despite the various criticisms and efforts that have been placed to eliminate this problem, it is now clear that psychologists have failed in their efforts to eliminate gender biases in their research agendas (Rick, 1). Consequently, this raises important questions about the psychology discipline, especially with reference to its approach towards gender differences. As a result, this outwardly indicates that this is an area ...

Psychology: Theoretical Concepts in Practice

Observation 1
Location: A blog article posted on The Wall Street Journal (http://blogs.wsj.com/economics/tag/education/)
The article reviewed a study that had been released a few days earlier that had reached a conclusion that popular kids in high school earn more later on in life than their counterparts (Derby, 2012). In his review, Derby (2012) observed that the study, which was published by the National Bureau of Research, suggested that popularity is not an inborn personality trait, but rather a trait that can be acquired through building social skills and benefits the individuals.

Introduction to Psychological Research Methods

A community living close to an industrial area has raised concerns about contaminants from industry causing health problems in local families. Based on current research, the public health guidelines state that children should not have blood lead levels above 10 micrograms per decilitre, because elevated lead levels may cause long-term cognitive impairment. As part of the investigation, parents of all children in the 2- to 6-year-old age range who live within a 10km radius of the industrial area are contacted and strongly encouraged to have their children assessed. Lead levels in the children’s blood of are measured. Blood samples ...

Introduction
Modern psychology relies primarily in experimentation. Since animals and human beings constitute the subjects of experimentation, precautionary measures continue to improve the process of experimentation while producing the less possible amount of damage to animals or human beings. Thus, different models, approaches and theories keep coming up as to how to do experimentation in psychology for furthering research.
Danziger (1985) writes that the experimentation in psychology has evolved as a social institution (Danziger, 1985, p. 133). Similarly, Schultz (1970) recognizes that modern psychological experimentation is the result of a long history of developments that have shaped this science ...

1. Factor Analysis
Factor analysis is a statistical procedure utilized for data reduction (Bartholomew et al., 2008). This reduction is reflected in lowering a large number of variables that have similar characteristics, into smaller factors (dimensions). Specifically, based on data reduction, factor analysis is conducted to identify the unobservable and underlying structure of a set of variables which are correlated with each other. These variables are coherent but independent of one another. By coherent it implies that the variables are very consistent and relate with each other harmoniously while independent denotes that the outcomes or the results of each variable are ...

Social Psychology

Correlation is contrasting two sets of measurements also called variables and determining how they are interrelated but should already be in existence (Dimitrios, 2011). This allows researchers make prediction based on only one variable (Elisa, 2007). A good example would be the relationship between murder rates and owning guns. Research has shown that there are higher murder occurrences in areas where gun ownership rates were high. This is an example of positive correlation because as the number of gun ownership increase so does the rates of murder.

Deception in psychological research is whereby the researcher neglects to tell the ...

Alternative hypothesis

An alternative hypothesis is a statement or assertion that the parameter of the population (mean, variance or proportion) differs from the value expressed by the null hypothesis.

Generally, hypothesis is a statement or assertion about the parameter of a population. In psychological research, there is a statement that is usually tested to come up with a general conclusion about the characteristic of population under study. The null hypothesis (a statement that the parameter of the population like the mean or proportion is equal to a specified value) is the statement that is usually tested, however, when the null hypothesis is not right, there is always a statement ...

Psychology as a science is being acted on by a number of values. What is wrong or right in the psychological sense has to be proven scientifically through fundamental research and empirical data.
A part from what is right or what is not measurerable, the psychological research has to be accepted by the norms of the society. For instance, this branch of science has to offer investigations into the societal acceptabilities in particular instances. Some communities for example consider certain practices to be taboos as compared to others. Psychology fails to show the universality that exists between what is considered ...

Asch’s Study of Conformity

In 1955, Solomon Eliot Asch carried out an investigation into human conformity as a social psychology study. Asch was interested in discovering under which circumstances people would be most inclined to conform. This study was pivotal in our developing understanding of social psychology as the better our knowledge of this, the less chance we have of being manipulated by others for their own ends.

The study itself focused on a group of several, male college students; they were told they would be examining line lengths in a study of ‘visual judgement.’ The men were shown one white card with one dark line ...
