In case studies there is an aim rather than a hypothesis like an experiment has, which indicates what the psychologist intend to find out and the reason for their investigations. Case studies are also often used to help individuals through a longitudinal study, where the research was collect over a space of time. For example, in the case of Genie, the aim was to try and develop as an individual and protect her from further psychological harm. Whereas in an experiment null, one-tailed or two-tailed hypotheses are made to predict conclusions. Freud used a variety of qualitative methods of data collection, such as, free association, dream analysis and slips of the tongue to uncover unconscious desires, often including death and sexual references.

Compare and Contrast Correlational Studies with Case Studies. Psychology has several different study research tools that can be used to investigate a topic of interest. Two types of studies that can be used are Correlational study or Case study. Both have positive and negative effects. Although, both are great study tools that have an outcome, which can be further investigated.
This paper will provide a clear definition of Social Psychology, a comparison of Social Psychology to other disciplines of psychology and an understanding of the role research plays. Definition of Social Psychology Social Psychology is defined as “the scientific study of how people think about, influence and relate to one another” (Myers, 2010, p. 4). Social Psychology is not about looking at one’s social influences. In order to understand it, one must be able to see how personality, attitude, and behavior- influences and are influenced by one’s social groups. This is primarily where Social Psychology would differ from Sociology.
Research, Statistics and Psychology Eric Ransome January 13, 2014 PSY/315 Racheal Reavy Research, Statistics and Psychology Research Statistics is one method that researchers use to tells the story of studies begin conducted. Research is the pursuit of knowledge, in the field of psychology statistics is used to understand the data collected from research. In psychology, research has a major role and it is statistics that helps to explain the information collected from research. The experimental or scientific study which gathers information on a subject is how research is defined. In psychology there are two essential elements in understanding theories and human behavior that is research and statistics, and how do we make sense of this information and the data collected.
What are the similarities and differences between qualitative and quantitative research? Qualitative research is deals with collecting descriptive information that cannot be definitely measured on an exact scale, often things that are observed. Examples would be emotions or feelings, attitudes, behavior, etc. It is a research method for exploring issues and topics in an attempt to understand them better and obtain answers and in some cases find similarities. Qualitative research is used in business research, market research and even scientific research.
The alternative hypothesis is the hypothesis that sample observations are influenced by some non-random cause. 3. What is a test statistic? (0.5 points) A statistic is a single measure of some attribute of a sample. It is calculated by applying a function (statistical algorithm) to the values of the items of the sample, which are known together as a set of data.
The slope b is the approximate change in y when x increases by 1. 2. How do you use the regression line for prediction? To make a prediction when you have population data, take average of group; group averages very often form line, also to make a prediction when you have a sample, take all group averages and draw a line of best fit; use line to predict. Regression models are often constructed based on certain conditions that must be verified for the model to fit the data well, and to be able to predict accurately.
The statistical test that was used by the researcher was Correlation. Correlation is a test used to show statistical relation between variables. The relation can be between things but in for the purpose of statistics is the relation between statistical variables which tend to vary or change together. This can be by all increasing or decreasing or by some increasing at a pace that the other decreases. For statistical purposes this correlation is not based only on chance.
Social Psychology and Multicultural Psychology Paper Define social psychology. With the mind being the axis in which social behavior pivots around, social psychologists will study what the relationship is between a person’s mind and their social behavior. Social psychology it will try to attempt to understand what the relationship is between the mind, social groups, and social behavior in three different ways. The first way would be that they try to understand how people’s thoughts, their feelings, and their behaviors, will be influenced by the actual presence, the imagined presence, or even the implied presence of other people. The second way would be to try to understand what the influence is on a person’s perception and on their behavior when it comes to the behavior of a social group.
