IHSTAT is a excel worksheet that enables statistical analyses of occupational hygiene measurement data and compliance testing (with occupational exposure limits).  IHSTAT was developed by AIHA (American Industrial Hygiene Association).

Determines whether samples are normally distributed or log normally distributed. Where:

IHSTAT is a excel worksheet that enables statistical analyses of occupational hygiene measurement data and compliance testing (with occupational exposure limits).  IHSTAT was developed by AIHA (American Industrial Hygiene Association).

  1. Determines whether samples are normally distributed or log normally distributed.
    Where:

    • Normal distribution – data that clusters around a mean/average
    • Log Normal distribution – the logarithm of data is normally distributed
  2. Determines percentage of samples that exceed the occupational exposure limit
