Total number of accidents multiplied by one million and divided for total worked hours.
AF= (Number of accidents * 1x10^6)/Worked Hours
Total number of accidents - Accidents that had result in absence to work. That had originated lost days.
Total worked hours - Number of worked hours done by all employees in that period. Incluing extra hours of work, excluding holidays, etc.
I Din't Know
(No. of Reportable Accidents * 100,000) / Total No. of Hours Worked for all Employees = AFR
A lower accident frequency rate is better as "frequency" means "how often something occurs".
accident frequency rate = accidents with lost time x 1.000.000 / manhours worked
500 manpower X 40 hours a week X 50 weeks per year = 1000000
You can calculate a wave's frequency by dividing the speed of the wave by its wavelength. The formula is: frequency = speed of wave / wavelength.
c=frequency x wavelength

fatal accident rate is number of fatal accidents x 100,000 divided by the total hours worked. Accident incident rate is the total number of accidents x 100,000 divided by the total hours worked. accident severity rate is the total days lost x 1,000 divided by the total hours worked
Number of accidents divided by time.
speed=frequency x wavelenth xD
To calculate cumulative frequency, you first need to have a frequency distribution table. Start by adding up the frequencies of the first category. Then, for each subsequent category, add the frequency to the cumulative frequency of the previous category. The final cumulative frequency will be the total number of observations in the data set.
