I am titrating NaOh and oxalic acid at school and got extremely weird results
1. 27 mL
2. 26.6 mL
3.26 mL
4.25.5 mL
5. 25.3mL

For the last three I was extremely careful, washed out my equipment very carefully and added the oxalic acid through a burette drop by drop.

Can I take an average of these results and and accept it as the final answer. I'm unsure because they are really off.

you should only take an average of the ones that werent rough, probably exclude the first two seeing as you stated you did the last 3 with care
