We were given an experiment in which the %age uncertainty of majority of students happened to be greater than 100?
What if the expected result in an experiment is zero? What is the percent uncertainty then?Asad Raza said:Why the uncertainty can not be greater than 100%. Prove it logically?
I don't understand why you are asking the question. You already have data in front of you where the relative uncertainty is greater than 100%, so clearly using that data you can demonstrate that the relative uncertainty can be greater than 100%.Asad Raza said:We were given an experiment in which the %age uncertainty of majority of students happened to be greater than 100?
Yes, the percentage uncertainty can be greater than 100% if the uncertainty in the measurement is larger than the measured value itself. This can happen, for example, when the measurement is very small or when there is a large amount of error in the measurement process.
No, the percentage uncertainty cannot be negative. This is because uncertainty is a measure of the potential error or deviation in a measurement, and it cannot be negative. If the uncertainty is calculated to be negative, it is likely that there was an error in the measurement or calculation process.
The percentage uncertainty represents the potential error or deviation in a measurement. A larger percentage uncertainty means that there is a higher chance that the measured value is further from the true value. Therefore, a higher percentage uncertainty can decrease the accuracy of a measurement.
No, there is no limit to how high the percentage uncertainty can be. However, if the uncertainty is larger than the measured value, the percentage uncertainty will be greater than 100%. In most cases, a percentage uncertainty of 100% or higher indicates a significant amount of error in the measurement.
The percentage uncertainty can be reduced by improving the precision and accuracy of the measurement process. This can be achieved by using more precise measuring instruments, taking multiple measurements, and minimizing sources of error. The percentage uncertainty can also be reduced by increasing the magnitude of the measured value, as the uncertainty will become a smaller proportion of the overall value.
