Definition
A method of evaluating test results by examining the numerical performance of each question across a group of students to determine how well the question discriminates between strong and weak learners, how difficult it was, and whether each answer choice functioned as intended.
Plain English
Looking at how students answered each test question, using simple math, to find out which questions worked well and which ones need to be rewritten or thrown out.
Context Anchor
In the Aviation Instructor’s Handbook, this term appears in the context of evaluating questions, answers, tests, or training results in a more objective way.
Derivation
From Latin status, meaning 'state' or 'condition,' which became 'statistics' — the study of numerical facts about a group. 'Analysis' comes from Greek analuein, 'to break apart.' Together: breaking the numbers apart to see what they reveal.
Why Pilots Care
Allows instructors to base training decisions on actual performance data rather than assumptions, improving safety and learning efficiency.
Intuition Check
Statistical analysis is not just having numbers. The numbers have to be organized and examined so they support a clear conclusion.
Example Sentence 1
After the end-of-course exam, the chief instructor ran a statistical analysis on each question to see which ones most students missed.
Example Sentence 2
After reviewing training records with statistical analysis, the instructor noticed a pattern in altitude deviations during solo flights.
