Hello guys,(adsbygoogle = window.adsbygoogle || []).push({});

can you explain something to me please?

Hmm.. looking for a way to insert an image. Well, just the link then: image here!

The blurry variables-things on the left are different input parameters, these are divided into 4 groups (top 1-4). Now I wonder what all the numbers mean. This is what I think:

Mean: the mean of all values inside a group

Standard deviation: deviation from mean

Mean variance: tricky. Under mean-variance I can only find strange financial explanations, under 'variance': how possible values are spread out around an expected value

Right, but what does that mean? Can I say with these information how the variables are represented within a group? Can I say something about the quality of this representation and if so, what would be a good representation? If I'm totally wrong, what can I actually do with this?

thanks a lot,

corinnagirl
