In statistical tests there are 2 main types of Errors, Type I and Type II. Type 1 errors occur when you reject a null hypothesis that is actually true and is thus refereed to as a false positive. Type II errors are essentially the opposite, accepting a null hypothesis that is false, and is often called a false negative. You can reduce the risk of a type I error by lowering the value of P that you're significance test must return to reject the null, but doing so will increase the chance of a type II error. The only way to reduce both is to increase the entire sample size. Alternatively, in some cases, it may also be possible to lower the standard deviation of the experiment, which would also decrease the risk of type I and type II errors.

How do you overcome or reduce the problem of random error and systematic error while doing an experiment-?
You can overcome or reduce the problem of random error and systematic error while doing an experiment by increasing the sample size, which means averaging over a huge number of observations.
How can you reduce the standard error in research?
Increase n or sample size.
Difference between biased and unbiased errors?
A biased error is one that is caused by a factor inherent to the source of the error. An unbiased error is one that comes from anywhere.
How do you reduce error in an experiment?
use proper instruements. make sure to follow care and use
Reduce type 1 error?
Accept lower p-values (meaning lower in magnitude; values tending toward zero).--And don't forget that by reducing the probability of getting a type I error, you increase the probability of getting a type II error (inverse relationship).
What factor can a researcher control that will reduce the type 1 error?
The significance level can be reduced.
What factor can a researcher control that will reduce the standard error?
In any experimental test there are factors that can contribute to error. For example in a biochemical test if you add the compounds with a faulty pippete then the amount of reagent per sample would vary and that would contribute to a noisy measurement. So by controlling experimental conditions as best as one is able error can be reduced. Never completely eliminated, but managed.
How can reduce the percentage error?
The larger the sample, the lower the % error.. so to reduce a % error, increase your sample size.
How to reduce scrap in a machining process?

how to decrease margin of error in probability sampling?
With probability sampling you have no control over the units that are sampled. So the only way to reduce the margin of error is to increase the size of the sample.
How do you reduce systematic error?
Systematic error is the result of complete equilibrium. The method to reduce systematic error is to introduce a proof that demonstrates the group has error in their consensus.
Define error control Describe stop and wait error control?

How do you reduce error in measurement?
take reading 4 to 5 times, and take its average this will reduce error
What is the Difference between data link error control and transport layer error control in osi model?
Data link error control checks for error in each router and end-system, but transport layer error control checks for error only at the end-systems.
How does increasing the sample size affect the sample error of the mean?
It should reduce the sample error.
How to reduce Margin of error?
Increase sample size.
