Here we can see that there is not much difference between the two groups alocholic and control having the subject S2.

You can see the distribution of both the group are nearly identical having no much quantifiable difference

Here we can that for sensor position P3,FZ,Y,PZ,FCZ,C6 we have some significant difference between the two groups and their their distriutions

We have almost the graph of both group for all sensor positions to have a look and understand  the differences between the two and also the describtion of both groups have been printed
