Calculate POINTS NEEDED with known Standard Error and V_{V} | |
---|---|
Coverage of object as a fraction of 1 (0 to 1): | fraction (V_{V}) |
Desired margin of error in % (>0 to 100): | % error (E) |
The Answer: | |
Point counts required: | points (P_{T}) |
Calculate STANDARD ERROR with known P_{T} & V_{V} | |
---|---|
Coverage of object as a fraction of 1 (0 to 1): | fraction (V_{V}) |
Number of points counted: | points (P_{T}) |
The Answer: | |
margin of error in %: | % error (E) |
This is based on the equation: P_{t} = 0.453 * (1 - V_{V}) / (V_{V} * E^{2})
