I've been looking at the frequency of the digits of pi in base 2. So far up to the first 400 bits, 0 occurs 57% of the time, 1 occurs 43 % of the time. Running a chi-square test on this gives a result of this being random of only 7%. In other words with this initial sample, there is enough of a bias to warrant further testing. I also ran a test on 2 digit bits and the bias is even stronger. Does anyone know of a site that has pi in base 2 or am i going to have to convert a base 10 site?
