For one data set I need label, so I use average of rows for that, now the question is that: why with a simple label the accuracy is very low and why if I use average as an attribute then according to the average I made "UP" and "DOWN" label, the accuracy is 95%?
What is your idea about it?
Is average bring correlation for data? ( I think correlation is not good in data) so why the result is not normal?
Except average what is your suggestion in statistics?
Thank you in advance
