USMC OFF-DUTY/RECREATIONAL FATALITIES
• UCI = Upper Confidence Interval LCI = Lower Confidence Interval
• Rate values above the UCI or below the LCI infer a statistically significant change is probable. This is only an indicator. Significance cannot be determined until end-of-year.
• Values between the UCI and LCI infer that nothing significant has occurred to increase or decrease mishap rate.
(Confidence Interval is based on: Poisson Rate related to a Chi Squared Distribution and calculated using FY14-18 data except for the Lost Work Days and Lost Time Case slides which were based on a normal distribution).
