In physics multiple choice papers, the correct answers should follow Benford’s law while the other options should not. So can an enterprising student use this to beat the test?
Back in the 1930s, the American physicist Frank Benford discovered that the first digit in certain lists of numbers was much more likely to be a 1 than a 9. He tested this idea on a variety of datasets such as the surface area of rivers, a list of physical constants and even the street addresses of the first 342 entries in American Men of Science.
