The actual error in X would be rX? And rθ?haruspex said:
Yes. So what is the fractional error in theta?Janiceleong26 said:
r ?haruspex said:
Right. Can you now see why A is wrong?Janiceleong26 said:
No ..sorry..haruspex said:
No, the percentage uncertainty is 100x fractional uncertainty.Janiceleong26 said:
What's the difference between fractional uncertainty and fractional error?haruspex said:
Sorry, I didn't notice I had switched from uncertainty to error. For the purposes of this question it makes no difference.Janiceleong26 said:
Ohhhh...is it because the percentage uncertainty would be the same for all values of θ, but the uncertainty itself varies?haruspex said:
Yes.Janiceleong26 said:

Calculating uncertainty allows scientists to determine the reliability and accuracy of their experimental results. It also helps in identifying potential errors and improving the experimental design.
Uncertainty is typically calculated by finding the standard deviation of the measured values and using it to determine the range of possible values. This can be done using statistical tools or mathematical formulas such as the propagation of uncertainty.
θ, also known as theta, is a symbol used to represent the uncertainty or error in a measurement. It is used in mathematical formulas to calculate the uncertainty of a particular value.
Changing θ can significantly affect the calculated uncertainty. A larger θ value indicates a larger uncertainty, while a smaller θ value indicates a smaller uncertainty. Therefore, it is important to carefully consider and accurately estimate θ in order to obtain reliable results.
No, uncertainty cannot be completely eliminated in scientific experiments. This is because all measurements have some degree of error and there will always be some level of uncertainty associated with them. However, by carefully controlling variables and accurately estimating θ, uncertainty can be minimized to a certain extent.
