Mnemonic Device for continuity correction

In this mnemonic you should remember that X was equal to something.

This is sometimes called as Normal Distribution as an approximation to Binomial Distribution.

ADD == Addition of  0.5

SUBTRACT  === Subtraction of  0.5



X  >   ( Because of addition)         ----------------------- ADD      

X  <   ( Because of substraction )  ---------------------- SUBTRACT             

X  ≥    ( Because of substraction )  ---------------------  SUBTRACT                   

X  ≤    ( Because of Addition )          ---------------------  ADD              

X  =   P ( -0.5 ≤ V ≤ + 0.5)
