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.
What can be done to reduce bias in sampling?
The thing that can be done to reduce bias is sampling random things
What is a random sample?
A random sample is a selection from the population of interest where each item (persons, households, widgets, etc.) has an equal chance of being selected. The idea being that measuring a random sample of sufficient size will accurately (within a margin of error) reflect the "true" value that exists in the population - while at the same time reducing your study to a manageable size. A random sample is integral in good survey design to reduce bias in your experiment.
How do you reduce error in an experiment?
use proper instruements. make sure to follow care and use
Why is a large sample better than a small sample?
A large sample will reduce the effects of random variations.

Why do you need to repeat your experiment?
To reduce Random and Systematic errors that may have occured during the experiment, by taking their average. This can get the most accurate value.
What are the advantages of stratified random sampling?
There are many advantages of using the stratified random sampling. Some of them are, ability to reduce human potential in choosing the cases in sample, statistical conclusion fro data collected, improving representation of strata etc.

Why do you have the rule that to improve answers you must have an account?
This is probably to reduce cases of vandalism - people writing random giberish, or otherwise inappropriate stuff.
How could you improve the experiment to reduce the effect of anomalous results?
repeating it
Why would you try to collect 5 or more results in an experiment?
I'm assuming that your experiment was one where systematic and random errors could've occurred, yes? Simply, it is to reduce the possibility of any inaccuracies, because from collecting 5 measurements you are able to obtain an average and also judge each measurement individually to see the differences. It really will just prove whether the conducting of the experiment was consistent in correlation to the results attained.

Can increasing sample size reduce random error?
Random error and sample size have an inverse relationship...As sample size INCREASES random error DECREASES. There's a good explanation at the related link.
How can we reduce illiterate people?
Reduce illetrate people
How can one reduce their tax debt?
There are many ways one can reduce tax debt. One can reduce their tax debt by hiring a tax professional, re-checking tax returns, and choosing a debt plan.
