Calculate POINTS NEEDED with known Standard Error and VV
Coverage of object as a fraction of 1 (0 to 1):	fraction (VV)
Desired margin of error in % (>0 to 100):	% error (E)
The Answer:
Point counts required:	points (PT)

 

Calculate STANDARD ERROR with known PT & VV
Coverage of object as a fraction of 1 (0 to 1):	fraction (VV)
Number of points counted:	points (PT)
The Answer:
margin of error in %:	% error (E)

This is based on the equation: P_t = 0.453 * (1 - V_V) / (V_V * E²)
