If the study is qualitative, personal bias can skew the data. Lab study subjects should be debriefed for the reason for the study after participation has ended. The researcher should take responsibility for the safety of the subjects. They should not be subjected to physical or mental abuse. The data reported must not be misrepresented or distorted.
STAT 1008 Assignment One Question 1 (a) The main purpose of statistics is that when the size of the population is not manageable, a sample of manageable size should be drawn from the population. While we are ultimately interested in some numerical aspect of the population, we also hope that some numerical aspect of the sample would reflect the numerical aspect of the population that we are interested in. Thus, there is no need to use census. (b) Stratified sampling is recommended. Stratified sampling is commonly used in the scenario described in the assignment spec.
Examples of a null hypothesis are: "There is no difference in mean weight between males and females" or "Patients' outcomes are no different with or without the surgical procedure." The alternative hypothesis represents the result that the experiment would like to show. The alternative hypothesis can be stated in terms simple inequality ("Male and female weights are different"), or can be stated in terms of a result on one side or the other of the equals sign ("Females weigh less than males"). Suppose you want to design an experiment to test whether two variables are related in a certain way. What you actually do is calculate the probability, based on your data, that the variables are not related in the way you suspect.
Lanier Technical College PSYC 1010 Critical Thinking Design Your Own Research Study The Assignment The assignment is to complete a research study testing the psychological concept of your choice. You will conduct your research by surveying individuals that represent your designated population. You will work out your study, and write your paper following APA format. Data analysis must be completed and include graphs and inferential statistics. Picking your topic For this project, you may choose to do an experiment, a correlation study, or case study experiment answering any question related to psychology.
Another important aspect of research is the process of scientific theory construction and testing. Scientific theory construction and testing is an intricate and important part of psychology research. The first step is to propose a theory, which is a set of interrelated ideas that explain a set of observations (Shaughnessy, Zechmeister, & Zechmeister,
You may also describe the measures you will take to minimize these risks and discomforts.) Potential benefits There are no known benefits to you that would result from your participation in this research. OR (Describe any benefits to the participant and to others that may reasonably be expected from the research.) This research may help us to understand (brief statement, if appropriate). Protection of confidentiality (Describe the extent to which confidentiality of records identifying the participant will be maintained.
Personality Assessment and Theories Cynthia Harding BEH/225 September 29, 2012 Serena Watts-Kumar, Instructor Personality Assessment and Theories “Personality refers to an individual’s unique pattern of thoughts, feelings, and behaviors that persists over time and across situations” (Morris & Maisto, 2010, p.359). There are four theories that explain different approaches to personality assessment. The four approaches are psychodynamic, humanistic, trait, and social learning. Personality is measured by psychologist with an assessment using four basic tools: personal interview, the objective tests, projective test, and direct observation of behavior. The different theories use different methods for assessing the personality.
Social Psychology Tandy Noonan Learning and Cognition/PSY400 12/19/2011 Dave Brueshoff Social Psychology Definition Paper How do we define Social Psychology and what influences does it have on individuals? When one understands social psychology they will be able to help others in being the best they can. In this paper you will find the definition of social psychology. Along with the definition of social psychology, you will find a discussion on how social psychology is different from sociology. Defining social psychology "Social psychology is a science that studies the influences of our situation, with special attention to how we view and affect one another; social psychology is the scientific study of how people think about; influenced, and relate to one another.
Rigor and control of extraneous variables allow researchers to establish a cause-effect relationships testing casual relationships (Polit and Beck, 2012).Experimental designs strengths are that a researcher gains first hand knowledge based on the use of actual tests and trials. The weaknesses are that outcomes may not be the most desirable and may be cause for a major effect up to the death of a patient. There is also the subject of ethics, how much exposure to experimental research is considered enough or is justified. Nonexperimental design Arnold (1997) comes in many forms and generally refers to research that does not employ randomization and control groups (p.44) .This is a non intrusive way to research. Based on actual fact and findings one can discover the actual results needed.
The case study has been used as a tool for natural and social sciences as well as psychological research. One type of case study is a “psychobiography” which means a researcher utilizes psychological theory to explain the life of an individual, usually an important historical figure. Reasons to Use Case studies can aid as being valuable for informing of conditions that are considered rare or unusual, thus providing unique data about psychological phenomenon like memory, social exchange, or language. Depending on the purpose, a case study may present an individual’s history, symptoms, characteristic behaviors, reactions to situations, or responses to treatment. Case studies are also useful for testing whether scientific theories and models
