What is the NUMi?
NUMi stands for Numeracy Understanding in Medicine Instrument, an objective test of health numeracy that is appropriate for both research and clinical settings. The NUMi will indicate how well a person will understand education materials, instructions, or other forms of communication that involve numbers, tables, & graphs, probability or statistics. The NUMi was developed and validated using item response theory (Med Decis Making 2012;32:851-865)
