Class 2: Research Methods in Psychology Quiz

Purpose of Literature Review and Hypothesis Development

• The purpose of a literature review in psychological research is to critically evaluate existing research on a research topic.
• After developing a testable hypothesis, the next step in the scientific method is to design a study to test the hypothesis.

Research Design and Data Analysis

• The step that involves placing raw data in statistical equations to support a hypothesis is called data analysis.
• The main purpose of operationally defining variables in psychological research is to clearly specify the variables being measured and how they will be measured.
• Reliability measures the consistency of a measurement tool or method in producing similar results.

Research Ethics

• The term 'generalizability' refers to the extent to which research findings can be applied to other populations or contexts.
• If a researcher does not provide informed consent to participants, the ethical principle of autonomy is violated.
• The main role of an Institutional Review Board (IRB) in research studies is to ensure that the study is conducted ethically and protects the rights and welfare of participants.
• Research ethics involve balancing a researcher's right to study behavior with the rights and welfare of participants.

Correlation and Experimental Research

• The main difference between positive and negative correlation is the direction of the relationship between variables.
• In experimental research, the purpose of a control group is to provide a baseline or comparison group against which the experimental group can be compared.
• A placebo in an experimental study is a neutral or inactive treatment used as a comparison to a real treatment.

Study Designs

• Cross-sectional research measures individuals of different ages at one point in time.
• Longitudinal research is distinguished from cross-sectional research in that it involves measuring the same individuals over time.
• Voluntary participation is a research design feature that ensures participants can withdraw from the study at any time.
• Informed consent ensures that participants are informed about the purpose, risks, and expectations of a study.

Biopsychology and Null Hypothesis

• The focus of study in biopsychology is the relationship between the brain and behavior.
• The purpose of the null hypothesis in statistical analysis is to provide a hypothesis that there is no significant difference or relationship between variables.
