And so it is presumably better to follow Galton and use the median as a group-guess. This turns out to be 1,775 beans. The true value was … 1,616.2 Just one person guessed this precisely, 45% of people guessed below 1,616, and 55% guessed above, so there was little systematic tendency for the guesses to be either on the high or low side – we say the true value lay at the 45th percentile of the empirical data distribution.
