A brief test measuring statistical numeracy and risk literacy through probability questions
About This Test
The Berlin Numeracy Test is a psychometrically sound instrument for quickly assessing statistical numeracy and risk literacy in adults. It can use an adaptive procedure that efficiently categorizes individuals into one of four competency levels using as few as 2-4 questions depending on performance. The test can be administered in adaptive or non-adaptive modes, with multiple choice or open-ended numeric response formats.
