empirical means we take what is given instead of trying to interpolate the data

#of Fs -------------- total # of grades

  • amistre64
in this case, if we go off your document 65/sum of it all

i thought u add all the number and divide by the number of the letter you looking for which is F
amistre64
  • amistre64
almost; you got the order flipped about. probability is defined as:\[\frac{\#.desired.outcomes}{\#.total.outcomes}\]
amistre64
  • amistre64
\[\frac{65}{sum.of.all}=\text{ empirical prob.}\]

65/600=.1083333333

# of Fs -------------- = emp. prob. total # of grades
amistre64
  • amistre64
if that 600 is good, then thats what it would amount to yes

  • anonymous
it total is 600
amistre64
  • amistre64
then the prob tends to truncate to 4 decis .1083 looks good to me
