Bachman's Formula

Bachman's Formula is a method used to estimate the knowledge a person has in a certain area. It combines three key factors: how many questions a person answers correctly, the total number of questions they were asked, and the difficulty of those questions. By analyzing these elements, the formula helps quantify a person's general knowledge in that field. This approach is useful in assessments and educational settings, providing insights into a person's understanding and expertise based on their performance on various questions.
