Using the table to determine the expected frequency of any given score
Lets suppose a shirt maker wants to determine how many shirts of a given neck size should be made.
We will assume:
- Average neck size is 15 and the SD is 2.
- formula:
- Fe=(iN/F)y
- Where
- I=size of interval
- N=number of shirts
- fe=(1000/2).3532 =176 size 16 shirts.
