Is it cheating on lab report homework if a peer points out calculation error that you then fix before submission? I am in a science class in which we have to write lab reports. Lab reports count for a significant part of our grade. I was working on my lab report but before I got to check over my calculations, a peer of mine mentioned the results he got. I realized that my results were different and saw that I had a very dumb calculation error. 

I am not sure if this is considered cheating because I am not sure if I would have noticed the mistake had I not heard from my peer (although I did plan on checking over my work). 

I was wondering if anyone had any opinions on this situation. I plan on telling my teacher exactly what happened tomorrow before handing in the report, I just feel really bad and guilty now. Any help/advice would be appreciated. Thank you!
I don't think this is cheating at all, unless you specifically asked peers of their results. 

The important thing is the understanding of the material. Your peer may well have been wrong in their answer and led you down the wrong path, but the important thing here is that you've double-checked your own work and recognised a mistake.
