Reproducibility trial: 246 biologists get different results from same data sets
Scientists who ran separate analyses on a single data set about the effect of grass cover on Eucalyptus seedlings arrived at vastly different answers.Credit: Laurence Dutton/Getty In a massive exercise to examine reproducibility, more than 200 biologists analysed the same sets of ecological data — and got widely divergent results. The first sweeping study1 of…
