In this interactive session, we will explore the standard statistical techniques and role of hypothesis testing in epidemiology and public heath. We will consider how statistics are used in actual convictions and miscarriages of justice. Discussion of the important implications of this for Letby and similar cases will be encouraged.
September 23 @ 13:30 - 14:15
What hypothesis test would you use to test whether the death rate on a medical unit has suddenly increased? How would you follow up a significant result which showed the risk of death had doubled?
The conviction of a UK nurse, Lucy Letby, for murdering seven newborn infants has resulted in debate about whether the conviction was safe. Investigating clusters of deaths, infectious diseases or collapses in healthcare settings pose various statistical challenges for forensic investigations.
In this interactive session, we will explore the standard statistical techniques and role of hypothesis testing in epidemiology and public heath. However, their use is not established within criminal investigations. We will consider how statistics are used in actual convictions and miscarriages of justice. Discussion of the important implications of this for Lucy Letby and similar cases will be encouraged.
