NormalBinomial
Or Poisson?
NORMAL
N=NATURAL
O=OSTANDARDDEVIATION
R=REAL LIFECONTINUOUS
M=MEAN
A=AREA UNDER
L= LAMBS An example of the normal curve is
the weight of new born lambs.
Binomial Distribution
Memory trick
bi
no
mi
al
biMeans two
There are TWO possible outcomesSuccess or Failure
noNo. stands for numberThere are a fixed number of identical trials.
Discrete – bar graph not histogram!
miMi sounds like me.
Me? I am dependent on no one!I am independent!
alAdd another l to get All
All trials have the SAME probabilityConstant probability!
How do I spot it?
Check each of the four conditions.You will be given, or be able to calculate the
probability p.You will be given the number of trials.
BPDBinomial Probability Distribution
Exactlya certain number (x) of successful trials
BCDBinomial Cumulative Distribution
Up to and includinga certain number (x)of successful trials
PPDPoisson Probability Distribution
Exactlya certain number (x)
of “occurrences of the event” with no upper limit
PCDPoisson Cumulative Distribution
Up to and includinga certain number (x)
of occurrences of the event
