I have 200 samples on one voltage. And because there is noise on the voltage and and want to reduce the noise affect on measured voltage and what i did is

add 200 samples together and t then divide 200

Voltage average= (sample1+ sample2+ .......sample200)/200

where sample1 is first sample voltage and sample200 is second sample of voltage. But the result has a some varations. because this applicaiton is very sensitive to small voltage.

I thought another way to calculate the average, use

__Quadratic mean__. or

__harmonic mean__, which is better to get average value and it will give better performance.

Are there any better ways to do it?

I am not good at math, Please give me some idea
