What are sources of error in principle of moments experiment?
Some sources of error in a principle of moments experiment include friction in the pivot point, inaccurate measurements of distances or forces, misalignment of the apparatus, and neglecting the weight of the beam. These errors can lead to discrepancies between the theoretical calculations and experimental results.
If a measurement is smaller does the percentage error increase or decrease?
increase
How can reduce the percentage error?
The larger the sample, the lower the % error.. so to reduce a % error, increase your sample size.
What happens to the confidence interval if you increase the margin of error?
It depends on whether it is the Type I Error or the Type II Error that is increased.
How to reduce Margin of error?
Increase sample size.
What combination of factors produces the smallest risk of a type 1 error?
A combination of factors increase the risk of a Type 1 error. Giving the wrong amount or wrong diagnosis for a wrong drug would certainly increase an error.
If given a sample size reducing the probability of a Type I error will increase the probablility of a Type II error?
Yes.
How can you reduce the standard error in research?
Increase n or sample size.
What happens to the damping when the settling time increases in a derivative error compensation?
increase
If the sample variance increases the estimated standard error will also increase?
true
If the size of the sample is increased the standard error?
If I have understood this very poorly worded question correctly, the answer is that the standard error may decrease. It cannot increase but it is possible that it does not decrease.
Does the probability of the type 1 error increase as the sample size increases?
No, the estimates should become more robust and the power of the test should, therefore, increase.
