How do I find the average value of variables

I've been adding all the values for each sprite and dividing it by the total number of sprites, is there anyway to do that? (Ex: for each sprite add sprite.size to Globalvariable then divide by the number of sprites is what I've been doing but is there some sort of function I can use instead?)

Create a Family with all the sprites. Then run a System > For Each loop SpriteFamily. i to SpriteFamily.Count (I think) GlobalVar + SpriteFamily.Size then divide the var by SpriteFamily.Count.

That's what I've been doing, I mean to ask is there any other way to do it? Like maybe some kind of function or something? I don't think there would be but I thought I'd ask

Well if there's is I haven't found it so I guess I'll just keep doing what I've been doing, it's just kind of annoying because with what I'm working on I'll have to do that a lot

And why would that be an issue?
Three lines, isn't that much?

I mean it isn't much I dunno I just thought there'd be some other way but there isn't so it's fine
