# How do accuracy and precision of measurement affect calculated values and percent error?

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

### Does percent uncertainty measure accuracy?

Accuracy STD on the other hand measures precision.

### 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 |.

### What is the percent uncertainty for the measurement given as 4.19m?

When giving the result of the measurement, its important to state the precision or estimated uncertainty, in the measurement. The percent uncertainty is simply the radio of the uncertainty to the measured value, multiplied by 100. 4.19m take the last decimal unit, is 9 but with value of 1/100 .01 is the uncertainty Now, .01/4.19 x 100 % = 0.24%

### How do you calculate the mean absolute percent error with a 0 actual value?

By definition of percent error, you can't. But you can approximate zero instead, with the number of decimals appropriate to the accuracy of the measurement, e.g. 0.01, 1E-100, etc.

### Why would one use root sum square for a calculation?

The square root of the sum of the squares (RSS) can be used to calculate the aggregate accuracy of a measurement when the accuracies of the all the measuring devices are known. The average accuracy is not merely the arithmetic average of the accuracies (or uncertainties), nor is it the sum of them. Let's say you are conducting a test to verify the resistance of a coil. The coil is built to have a resistance… Read More

### What is the percent error of the measurement 4 cm?

Percent error is calculated by the measured value and the acceped value. For example, if you measure a piece of paper and decide it is 8.45in long, that is your measured value. The package says it is 8.5in long, so it is the accepted value. The formula for percent error is |measured value - accepted value| divided by accepted value ALL times 100.
