8.9 - 0.2 = 8.7. That is an exact answer which is perfectly accurate. So the percentage error is 0.

percentage error is the difference from the actual value divided by actual value in 100,whereas subtracting the same value from one give u the percentage accuracy

"MAPE is commonly used in quantitative forecasting methods because it produces a measure of relative overall fit. The absolute values of all the percentage errors are summed up and the average is computed." (according to John Galt University)

The percentage error is how accurate your experimental values compared to the accepted value. The equation is: [(experimental value - accepted value) / accepted value] x 100

Zero error in a measuring instrument can lead to inaccuracies in measurements by causing a constant offset in readings. This can result in consistently higher or lower values than the true measurement, compromising the accuracy of the data collected. Calibrating the instrument and accounting for zero error can help improve the reliability of measurements.

False

The more precise your instruments of measurement are, the less percentage of error you will have.

A 0-10A ammeter has a guaranteed accuracy of 1.5% of full scale reading.The current measured by the instrument is 2.5A.Calculate the limitting values of current and the percentage limitting error.

A systematic error affects accuracy as it causes the measured values to deviate consistently from the true value. It does not affect precision, which is a measure of the reproducibility or repeatability of measurements.

In cosmology, 1 sigma error represents a range of values that includes about 68% of possible outcomes, while 2 sigma error represents a range of values that includes about 95% of possible outcomes. These errors help quantify the uncertainty in measurements and observations in cosmological studies.

The ratio of an error to an accepted value is called the relative error. It is a measure of how large the error is compared to the accepted value. By expressing the error relative to the accepted value, it allows for a standardized comparison between different measurements or experiments.

To reduce % error, you may- 1. Take an average over many observations. 2. Use the correct bridge for various measurements of resistance.(see variants of the wheatstone bridge)

Precision refers to the degree of agreement among repeated measurements of the same quantity. A measurement is considered precise if repeated measurements under the same conditions yield similar results. High precision means that the measurements are close to each other, while low precision implies variability in the measurements.
