I would have thought this blindingly obvious but no matter, a lower percentage error is better because it means your approximation to a solution is closer to the real answer than an approximation with a higher error.

How can reduce the percentage error?
The larger the sample, the lower the % error.. so to reduce a % error, increase your sample size.
Why do you use average percentage error and why is it better than mean error?
Percentage error shows how wrong an answer can be with respect to the value of the answer itself. So, we can see how serious the errors are. For example, lets say we have an answer whose mean error is 40. If nothing is given of the actual value of the answer, we cannot determine if this error is insignificant or very serious. If the actual answer was 40000, this mean error of 40 is quite insignificant as the percentage error is 40/40000 x 100 = 0.1 % 0.1 % error is quite insignificant. Mean error, on the other hand, does not help us to determine the significance of this error in any way.
How do you calculate percentage error for equipment?
Look on the equipment for where it says the plus or minus figure for accuracy (for a burette it is usually + and _ 0.1cm3) divide this by the amount you measured , times 100 to make it a percentage. ---- ---- Percentage Error = Maximum Error / Measured Value X 100 For example.Maximum Error for the following apparatus are:Balance = +/- 0.01Pippette = +/- 0.1 And the Measured value for each are:Balance = 0.15Pippette = 25 Then...the percentage error is:Balance percentage error = 0.01 / 0.15 X 100 = 66.66%Pippette percentage error = 0.1 / 25 X 100 = 0.3% You can now also work out your maximum total error.Maximum total Percentage error = Balance Percentage error + Pippette Percentage errorMaximum total percentage error = 66.66 + 0.4 = 67.06%
If a measurement is small is the percentage error high?
yes, it is. The smaller the measurement, the higher the percentage error.
What is the percentage error of 12m?
what is the percent error of 12m
With the mean absolute percentage error is a higher or lower number better?
The lower the better
How can reduce the percentage error?
The larger the sample, the lower the % error.. so to reduce a % error, increase your sample size.
Is a higher or lower root mean squared error better?
A lower.
What is better a higher or a lower percentage?
If you are receiving interest on an assett, a higher interest is better. If you are paying interest on a debit, a lower interest is better.
If a scientist records these measurements volume 13.2 ml mass 15.36 kg Which measurment has the lower percentage error?
15,36 kg
Find the percentage error in rounding 3.452 to 3.5?

What is error and percentage error?
Percentage error measures the error in relation to the quantity measured. For example if something weighs 100 grams with a possible error of plus or minus 5 grams, this is an error of 5%
If a measurement is small is the percentage error high?
yes, it is. The smaller the measurement, the higher the percentage error.
What is the percentage error of 12m?
what is the percent error of 12m
When an error of 1 percent is made in the length of a square the percentage error in the area of square will be?
The percentage error in the area of the square will be twice the percentage error in the length of the square. This is because the error in the length affects both the length and width of the square, resulting in a compounded effect on the area. Therefore, if there is a 1 percent error in the length, the percentage error in the area would be 2 percent.
