Hello, I was wondering does repeating affect just reliability or accuracy as well. As it could affect accuracy with the fact that you can identify and remove anomalies and then your mean would be closer to the true value. If no accuracy, how do you phrase it that accuracy is not affected

your question is rather unclear I'm afraid since these terms are used in different ways in different contexts. So rather than tell you something that may/may not fit what you are asking about have a look at these sites that define terms for slightly different contexts

If you are really talking about statistical terminology then bear in mind that accuracy is a different thing to precision

while reliability is often poorly defined but this site isn't bad
