Step-by-Step Guide: Understanding and Writing About Effect Sizes in Psychology
Step 1: Read and Understand the Chapter and Article
-
Carefully read the assigned chapter on effect sizes and the Cohen (1994) article. Focus on conceptual understanding rather than calculations.
-
Note key points about why effect sizes matter and how they are used in psychological research.
Step 2: Identify the Core Concepts
-
Understand that effect size measures the magnitude of a phenomenon, not just whether it is statistically significant.
-
Recognize that statistical significance (p-values) tells you if an effect exists, while effect size tells you how meaningful or impactful that effect is.
-
Cohen (1994) provides guidelines for interpreting small, medium, and large effects, which help in comparing results across studies.
Step 3: Describe the Importance of Effect Sizes
-
Effect sizes improve the interpretation of research findings by showing the practical significance of results.
-
They allow researchers to compare effects across different studies and populations, contributing to meta-analyses and broader understanding in psychology.
-
Effect sizes support evidence-based practice by helping practitioners understand whether interventions or treatments have a meaningful impact.
-
Highlight how effect sizes help avoid overemphasis on p-values, which can sometimes misrepresent the real-world importance of findings.
Step 4: Write Your Response
-
Begin with an introductory sentence defining effect sizes and their role in psychological research.
-
Explain how effect sizes complement statistical significance.
-
Discuss practical applications in psychology, such as evaluating therapy effectiveness, program interventions, or behavioral studies.
-
Conclude by summarizing why effect sizes are essential for advancing knowledge and evidence-based practices in psychology.
Step 5: Support Your Points with References
-
Cite Cohen (1994) and the chapter you read.
-
Optionally, add one or two scholarly articles that discuss effect sizes in applied psychology.
