This “statistics in slow motion” video is the best visual example that I have seen for understanding how statistics and probability work! It is highly unlikely that all of the beads will end up at the edges in any experiment – most will end up in the middle (i.e. normal distribution).
Important take aways from a long-term analysis of devil facial tumour disease #DFTD
1. “these results indicate that plasticity in devil life history traits, that are triggered by reduced densities, have allowed them to persist with the disease to date”
2. “results show that prevalence increased in 1-year-old devils with years since DFTD. Our results support the idea that the frequency of encounter in young devils increases as they breed younger and therefore increases their chances of contracting DFTD”
3. “precocial breeding may be a powerful offset to DFTD. We suspect that the rate of precocial breeding and the number of pouch young per female may be near maximum capacity in response to the reduced densities caused by DFTD”
