AB  - The available coefficient of friction (ACOF) is a measure of the friction 
      available between two surfaces, which for human gait would be the footwear-floor 
      interface. It is often compared to the required coefficient of friction (RCOF) to 
      determine the likelihood of a slip in gait. Both the ACOF and RCOF are stochastic 
      by nature meaning that neither should be represented by a deterministic value, 
      such as the sample mean. Previous research has determined that the RCOF can be 
      modelled well by either the normal or lognormal distributions, but previous 
      research aimed at determining an appropriate distribution for the ACOF was 
      inconclusive. This study focuses on modelling the stochastic nature of the ACOF 
      by fitting eight continuous probability distributions to ACOF data for six 
      scenarios. In addition, the data were used to study the effect that a simple 
      housekeeping action such as sweeping could have on the ACOF. Practitioner 
      Summary: Previous research aimed at determining an appropriate distribution for 
      the ACOF was inconclusive. The study addresses this issue as well as looking at 
      the effect that an act such as sweeping has on the ACOF.
