Question

[(exp value - accepted value)/accepted value]*100 = percent error.

For exp value, do I have to average my five trials?

Answer 1

Yes I think you do. You add them together and then divide by how many trials you had. Then use that value to plug into the exp value.

Answer 2

Personally, I would calculate the percent error of each trial, then do the averaging bit. You want to know the error of each sample you did AND you wnt to know the average. To calculate percent error ONLY on the average doesn't tell you anything about how accurate each titration was. But when all is said and done, you want the average percent error, too.

Answer 3

Percentage difference is the same as percentage error?

Answer 4

yes

Answer 5

Assuming, of course, that the difference we are measuring is the accepted value. But you can find the average results, then find the percent difference between the average and any one of the trials.
