How do you calculate error analysis?
For example; 200 +- 5%
Please explain if possible
Percent yield:
(actual value / theoretical value) x 100
Percent Error:
( | theoretical - actual | / theoretical) x 100
(same as 100 - % yeild)
Theo: is from stoichiometry or other math calculation
Actual: is what you actually optained in the lab - or given to you in a problem.
Thanks your explanation helped a lot :]
Your Welcome:)
To calculate error analysis, you need to understand the concept of percentage error. Percentage error is a measure of how much an observed or measured value deviates from the true value, expressed as a percentage.
In your example, 200 +- 5%, the value of 200 represents the observed or measured quantity, and 5% represents the percentage error.
To calculate the actual error amount, you first convert the percentage error into a decimal by dividing it by 100. In this case, 5% is equivalent to 0.05 (5/100).
To calculate the error amount, you multiply the observed quantity by the decimal representing the percentage error. So, for 200 +- 5%, the error amount would be:
Error = 200 * 0.05 = 10
Therefore, the calculated error is 10.
To analyze the error, you can then consider how it relates to the observed quantity. In this case, you can express the result as 200 ± 10, indicating that the measured value is potentially anywhere between 190 (200 - 10) to 210 (200 + 10).
Keep in mind that error analysis is an important aspect of scientific measurement and can provide valuable insights into the accuracy and precision of experimental results.
