How Do You Calculate Percentage Error in Period Measurements?

AI Thread Summary
To calculate the percentage error in period measurements, first determine the period from the timer's data, which involves dividing the total time by the number of cycles. The actual period is given as 0.020 seconds. The percentage error is calculated by taking the absolute difference between the measured period and the actual period, dividing by the actual period, and then multiplying by 100. A participant initially thought the percentage error was 91%, but it was clarified that this was incorrect. Accurate calculations and showing working steps are emphasized for clarity in the process.

Help please you all can do this

i am a noob at this here it is


1. Arecording timer makes 465 dots in 8.5s

(A) calculate its period . i have this but i don't know (B)
(B) Its actual period is 0.020s. calculate the percentage error


we are using the T=sec
----
cycles

First rule, then: show some working...
 
sorry i am not a pro like you but i suck at this but thjx for the help ass and i think it is 91 % but i am not 100%
 
You could at least show what you have for A

btw: 91% is right - what's your working?
 
thx man so 91 % is right kewl sorry for calling you a ass it sounded like you where being one

:biggrin:

That's OK - I've just woke up :biggrin:
 
Actually, 91% isn't the percentage error.

You're on the right lines tho' - if you got the 91%, you've got A, I presume...

Now take the difference between your vale of A and the actual value given, then work out the percentage error
