I'm pretty proficient with excel but I need help on something. I have to do an X-Y plot. I'm plotting averages of certain multiple trials, but I also have to calculate the standard deviation and the standard error of the individual trials and apply error bars to the graphs. Does anyone know a quick way to do this in excel? Or any tips other than doin this manually?

I think its tonight the orionid meteors are at their max. I just want to know has anyone seen any yet - seriously. (probably not we're all doing this!) I think you have to look after midnight. I saw a shower of leonid meteors once and it was bloody amazing, so don't want to miss these if they're gonna be as good and would recommend others having a quick look too.
