5 questions about the numerical tasks placed in medical content, total score is number of correct answers on those questions. The five questions are part of Numeracy Understanding in Medicine Instrument (Schapira et al, 2012), and we will translate only the questions focusing on Probability section. Cronbach's alpha in previous research was 0.86 (Schapira et al, 2012). The questions will be revised by independent translator and back translated to English.
