Median Statistics and the Hubble Constant

Following Gott et al., we use Huchra's final compilation of 553 measurements of the Hubble constant (H-0) to estimate median statistical constraints on H-0. Our median statistical analysis yields H-0 = 68 +/- 5.5 (or +/- 1) kms(-1) Mpc(-1), where the errors are the 95% statistical and systematic (or statistical) errors. These results are close to what Gott et al. found a decade ago, with smaller statistical errors and similar systematic errors. With about two-thirds more measurements, we are also able to clearly illustrate the presence and magnitude of systematic errors for different methods.
