GUIDE FOR THE WRITTEN CRITIQUE OF AN EXPERIMENTAL STUDY

Reference: APA style

Principle: Concise statement of relationship being investigated

Type of Design: Classify using Campbell and Stanley. Analyze by identifying measures and treatments as specific to the study.

Factors Jeopardizing Internal Validity: Identify type of factor (Campbell and Stanley) but be specific as to probable examples of the factors identified which operate in the study.

Factors Jeopardizing External Validity:

Adequacy of Statistical Procedures Used: Identify any inappropriate use of statistics to compare differences. Suggest improvements.

Briefly Summarize Logic (Inductive and/or Deductive): What line of reasoning is used to tie empirical results to the principle being investigated? Be concise. What assumptions are unstated? Are they reasonable?

Design Improvement: How could the design be modified to more adequately test hypothesis?

Extension of the study: What additional studies could be designed to extend the idea? Diagram and summarize very briefly.
