A large amount of results may make it easier to spot anomalies.

If you do an experiment just once, you could get an anomalous result. Do it twice, one could be anomalous, but they should be so different you realise one must be wrong.
Thats why most do experiments multiple times. The more times an experiment is repeated, the more anomalies stick out and can be discounted.

Too check for anomalies and to show that the results weren't by luck/random. If you repeat it many times then the data is considered more reliable as the chance of it all be down to luck/random is reduced. If that makes sense.

Repeating experiments has four major uses:
1) Repetition reduces the likelihood of errors or anomalous results (verification)
2) Scientists repeat others' experiments to verify the accuracy of the findings (peer review)
3) Repeating an experiment allows a person to refine the results or simplify the methodology
4) Scientists will often repeat experiments in order to study why it is that experiments bring about the results they do

Repeating it and recording the results would help make the experiment reliable to make sure there is nothing tampering with results. If there is a huge difference between each result, then something is wrong. Like others have mentioned, it prevent anomalous results.

Reduces the chance of an anomaly (a result which stands out from the others which is a flaw)

Reliable only
Your right in that repeating an experiment allows you to take an average of your results, which should be accurate, but there are a few different ways of getting an average.
Highest result - lowest result
Middle result
Most common result
These can be the same but often aren't, hardly accurate. Also the average result may not nessicarily be the most accurate. As you have said accuracy depends upon exact control of all variables and numbers.

i disagree, the more the numbers of the experiment the better the accuracy,
e.g 30 people do a questionnaire compared to 100
the 100 people is more accurate
learnt it in maths
'the bigger the sample so are the results.'
you find average of both results makes it more accurate
search it up.!!!!!!!
