Post More videos Key Questions What does accuracy in chemistry mean? If a measurement is accurate, that means that it's close to the actual value of the thing being measured. For example, if my cat weighs 6500 grams and a scale said it weighed 6400 grams, this measurement would have moderately good accuracy. OK. misterguch · 1 · 1 comment · Jul 3 2014 How can precision be measured? To measure precision, just measure something a whole bunch of times with some measuring tool. If you get the same answer every time, you've got a precise measurement. Typically, precision manifests itself in the number of

The definition of percent error uses the absolute value of the difference between your value and the accepted value so it can never be negative.

the high percentage error of Impedance resistance (Rb or Rct) using Zview software? I am using Zview software to analyzed my impedance data, and after I select the https://www.researchgate.net/post/How_can_I_deal_with_the_high_percentage_error_of_Impedance_resistance_Rb_or_Rct_using_Zview_software suitable equivalent circuit and obtaining a good fitting (please see both Nyquist and Bode plots, attached files) I found that the barrier resistance has a start value and another end value with high percentage error. So, I don't know exactly what is the value of the barrier resistance (Rb)? And how can I eliminate this error, and Why did I obtain this high percentage percent error error although I have good fitting?

Share Facebook Twitter LinkedIn Google+ 0 / 0 Popular Answers Matthew Lacey · Uppsala University The reason is that the equivalent circuit isn't actually suitable and the parallel resistor element shouldn't be there. The plots provided are typical of just a resistance and CPE in series, which fits well. However, a second resistance in parallel with the CPE means that at lower frequency the system should tend towards the real (x-) axis again and show the well-known depressed semicircle shape. This behaviour cannot be seen, and the program can't fit to it - so it ends up regressing to give a resistor with an absurdly high value with a huge error - it's the program's way of saying the element shouldn't be there. You could extend the range of the measurement to include lower freque
