The question in full: Now that you have a better understanding of research methods, create and write one research question that could be answered by each of the following methods and explain why it is answered by each method: correlational research, experimental research, and case study. The attached file is just the textbook chapter describing research study methods.  Any decent psychology student should know that stuff already.

Research Methods: Correlational Research, Experimental Research, and Case Study

Introduction

In the field of psychology, various research methods are utilized to explore and understand different aspects of human behavior and mental processes. These methods serve as valuable tools to collect and analyze data in a systematic and objective manner. In this assignment, we will examine three distinct research methods: correlational research, experimental research, and case study. For each method, we will develop a research question and discuss how that particular method would be suitable for providing an answer.

Correlational Research

Research Question: How does the amount of exercise correlate with levels of happiness in adults?

Correlational research involves measuring the relationship between two or more variables without manipulating them. It seeks to determine the degree of association or correlation between variables and examine the direction and strength of that relationship. In the given research question, the researcher aims to explore the relationship between exercise and happiness levels among adults.

Correlational research is a suitable method to address this question because it allows for the examination of naturally occurring variables in their natural settings. By collecting data on individuals’ exercise habits and self-reported happiness levels, researchers can analyze the strength and direction of the relationship between these variables. This method is valuable when it is not feasible or ethical to manipulate variables.

Through correlational research, the researcher can investigate whether an increase in exercise is associated with higher levels of happiness in adults. A positive correlation would indicate that as exercise levels increase, happiness levels also tend to rise. Conversely, a negative correlation would suggest that as exercise decreases, happiness levels may also decrease. Additionally, no correlation would reveal no statistically significant relationship between the variables.

Experimental Research

Research Question: Does listening to classical music improve concentration in students?

Experimental research involves manipulating variables to determine cause and effect relationships. In an experimental design, the researcher actively controls and manipulates the independent variable while measuring the effect on the dependent variable. In this research question, the investigator aims to investigate the impact of listening to classical music on concentration levels in students.

Experimental research is suitable for this question as it allows for the manipulation of variables to establish cause and effect relationships. The researcher can randomly assign two groups of students: an experimental group who listen to classical music while studying and a control group who study in silence. By comparing the concentration levels of the two groups, the researcher can assess whether listening to classical music improves concentration.

The experimental design controls for external factors that may influence concentration levels, such as the environment or individual differences. By randomly assigning participants to groups, the researcher can ensure that any observed differences in concentration levels between the groups are directly attributed to the manipulation of the independent variable (listening to classical music).

Through experimental research, the researcher can determine whether listening to classical music has a causal effect on concentration levels in students. If the experimental group demonstrates significantly higher concentration levels compared to the control group, it suggests that classical music promotes improved focus. Conversely, if no significant difference is found, it implies that listening to classical music does not contribute to enhanced concentration in students.

Case Study

Research Question: What are the long-term psychological effects of childhood trauma on adult survivors?

A case study is an in-depth investigation of a single individual, group, or phenomenon. It involves a comprehensive exploration of a specific situation or experience, aiming to provide a detailed understanding of the topic under investigation. In the given research question, the researcher seeks to examine the long-term psychological effects of childhood trauma on adult survivors.

A case study design is appropriate for this research question because it allows for a deep and rich exploration of the psychological effects of childhood trauma. By focusing on individual cases, the researcher can gather extensive qualitative data, including interviews, observations, and archival records, to gain insight into the unique aspects of each survivor’s experience.

Through a case study, the researcher can explore the various dimensions of psychological effects experienced by adult survivors of childhood trauma. This method enables an in-depth examination of the long-term consequences on individual well-being, including emotional, cognitive, and behavioral outcomes. Case studies provide a holistic understanding of complex phenomena, offering valuable insights into the psychological processes associated with the experience of childhood trauma.

Conclusion

In this assignment, we have discussed three distinct research methods: correlational research, experimental research, and case study. Each method offers unique strengths and advantages in addressing different research questions. Correlational research is suitable for examining relationships between variables, experimental research allows for causal inferences, and case studies provide an in-depth understanding of specific cases or phenomena. Understanding the characteristics and applications of these research methods is crucial for conducting rigorous and meaningful research in the field of psychology.
