Discrepancy Between Upper and Lower 27%: The data shows that high-performing students (Upper 27%) did not consistently choose the correct answer, while lower-performing students (Lower 27%) selected incorrect options more frequently.

 Low Selection Rates for Certain Options: Some response choices have very low selection frequencies (3%-10%), indicating possible distractors that may not be functioning effectively.

 Potential Key Errors or Ambiguous Questions: If stronger students are not selecting the correct answer, the item may be flawed, misleading, or miskeyed.

 Review and Adjustment Required: The adjust answer checkmarks suggest a possible re-evaluation or rekeying of the correct response, ensuring fairness and validity in scoring.

Unselected Answer Choices (A, B, C): No response data is available for these options, suggesting they were not chosen by candidates or might have been poorly structured distractors that failed to attract responses. They should be reviewed for relevance.

Response Trends for D and E:

1. • D (Klinefelter’s syndrome): More lower-performing students (75%) selected this option compared to higher-performing students (33%), indicating a possible misconception or a misleading distractor.

   • E (MYCN gene amplification): The majority of high-performing candidates (67%) selected this option, making it a strong candidate for the correct answer.

Potential Answer Key Adjustments: The presence of checkmarks in the "Adjust Answer" column suggests a review or potential rekeying to ensure that scoring is fair and aligned with medical knowledge.

Actionable Insights:

1. • Consider rewording or replacing unselected answer choices (A, B, C) to ensure they are valid distractors.

   • Verify the correctness of D since weaker students selected it more often.

   • Confirm if E is the correct answer based on subject-matter expertise.
