Then the measured value is larger than the actual value.
%error = (Actual value- Measured value) / actual value *100
Accuracy
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.

In the Cartesian plane, an angle is measured in the anti-clockwise direction from the x-axis. A negative angle is measured in the clockwise direction from the x-axis. However, an angle is effectively the same if you add or subtract 360 degrees. So, if you are faced with a negative angle just keep adding 360 degrees until you have a positive value.
%error = (Actual value- Measured value) / actual value *100
an error is the difference between a predicted value and the actual value. % errors tell you how close or how far you came to the actual answer is the form of a percentage. Mathematically: [(accepted value-measured value) / accepted lValue] * 100% note: if your answer is negative it means you were, for example, 15% short of the actual answer
Inductance is not negative. It is measured in henrys, and that is a positive value. Inductive reactance, however, is measured in ohms, and is commonly shown as negative to indicate that the current lags the voltage.

Non-negative real numbers.
Depending on whether you subtract actual value from expected value or other way around, a positive or negative percent error, will tell you on which side of the expected value that your actual value is. For example, suppose your expected value is 24, and your actual value is 24.3 then if you do the following calculation to figure percent error:[percent error] = (actual value - expected value)/(actual value) - 1 --> then convert to percent.So you have (24.3 - 24)/24 -1 = .0125 --> 1.25%, which tells me the actual is higher than the expected. If instead, you subtracted the actual from the expected, then you would get a negative 1.25%, but your actual is still greater than the expected. My preference is to subtract the expected from the actual. That way a positive error tells you the actual is greater than expected, and a negative percent error tells you that the actual is less than the expected.

It's the similarity I think.
You think probable to the accuracy (in the English terminology); and this value is determined exparimentally in each case.
Typically, negative numbers could be "measured" by the difference between the number and another number. The magnitude of a negative number is the distance from zero. Essentially, remove the minus sign, and you have the magnitude (also called absolute value) of the number.
Systematic error is the difference between the actual value of what is being measured and the value you found. The results of systematic error are precise but not accurate.
