  <dc:description>This folder contains anonymized data from the experiment described in the paper "Wrong Answers for Wrong Reasons: The Risks of Ad Hoc Instruments".


	questions.md contains the 14 questions used as pre/post-test
	Participants are identified using numeric identifiers (from 1 to 40).
	conditions.csv contains the mapping between participants identifiers and their condition
	
	{test}_{assessment_type}_anon.csv contains data for a given test (pretest or posttest) using a certain assessment type. Two assessment types are used:

	
		mc (multiple choice as assessed by Moodle: 0 means wrong, 1 means correct, - means missing)
		revised (human revision after reading the explanation: the judgment is either a 0 or a 1 following what presented in the paper)
	
	
	
	Statistics are computed with Python and SciPy. You can execute the script by running:

	python3 main.py


	and you should get this output:

	=== Analyzing answers using mc as assessment type ===

	You might need to install scipy (e.g., depending on your setup, pip install scipy).
