Method and device for simplifying beta factor calculation

The invention discloses a method and a device for simplifying beta factor calculation. The method comprises the following steps: acquiring all question options and an X score and a Y score corresponding to each question option; counting a numerical value obtained by adding the X score and the Y score corresponding to each question option as M; acquiring a diagnosis range, a diagnosis time interval and a Z value corresponding to the diagnosis range and the diagnosis time interval for the channel with the diagnosis test function; counting a numerical value obtained by multiplying an X score corresponding to each question option by a Z value as N; determining whether each problem option accords with the actual situation of the scene; summarizing an M value and an N value of question options, and calculating an S value and an SD value; comparing the S value or the SD value with a set value range, and extracting a corresponding beta value or beta D value; and displaying the result. The device comprises an input mo
