What does a negative percentage error means?
A percentage error is 100*(measurement - true value)/true valueThe percentage error is negative if the measured (or calculated) value is smaller that the true value.
What does negative zero error mean?
There can't be a negative zero. zero is neither negative nor positive.
What is the difference between systematic error and accidental error?
Systematic error is a constant or known:effects of the error are cumulativeerror is always positive or negativeAccidental error is a unavoidable error: effects of the error is compensationerror is equally like to be positive or negative
What are beta values?
The probability that a statistical that will give give a false negative error.
Log -3 equals?
There is no answer - it is an error: negative numbers do not have logarithms. The log if a number tells to what power the (positive) base must be raised to get the number. Raising any positive number to any power will never result in a negative number, so it is an error to try and take the log of a negative number.
Can the relative error be negative?
It can be.
Can the error be positive or negative in finding relative error?
Yes.
Can percent error be negative?
Sometimes you will take the absolute value of the percent error because your estimated number could be less than the theoretical, meaning the calculation is negative. But an absolute value is always positive. A percent error can be left as a negative though, and this would be perfectly acceptable (or even preferred) depending on what you're doing.Answer:In the sciences, a negative percent error indicates a low result. If you have a 0% error, then your observed (lab) result was exactly the same as the theoretical result. A 5% error could mean that your observed result was a little high. A negative percent error is possible; if your observed results were lower than the expected, then you would have a negative percent error. A -5% error could mean that your results were a little low. Having a negative percent error isn't worse than positive percent error -- it could mean the same thing. If you were to have a choice in having a 20% error and a -5% error, the negative percent error is more accurate.

What does negative zero error mean?
There can't be a negative zero. zero is neither negative nor positive.
What do we do if our concentrations are negative?
Search for a calculation error.
What if the standard deviation is negative?
There is a calculation error.
What is the difference between systematic error and accidental error?
Systematic error is a constant or known:effects of the error are cumulativeerror is always positive or negativeAccidental error is a unavoidable error: effects of the error is compensationerror is equally like to be positive or negative
Did random error have positive value or negative value?
It must be either, otherwise it is systematic error or bias.
What is a Type II Error - a false-negative error?
Falling to reject (accepting) a false null hypothesis.
What is negative 9 equals 5 over 17?
An error
Percent error formula?
Divide the calculated or estimated error by the magnitude of the measurement. Take the absolute value of the result, that is, if it is negative, convert to positive. This would make the percent error = | error / measurement |.
