Just after a bit of advice (sensible only please :wink:) on some stats quoted in a report I'm proof reading/editing.
For background purposes - it's an Excel table with results of chemical analyses. They've given an average of 5 analyses of each specimen, and have shown the standard deviation for each 'element column'.
I've noticed that some of the trace elements have Std Devs almost as high as the average i.e. 0.32% average with 0.29% SD.
My feeling is that the average values with the high SD's should be disregarded in case they mislead - What do people think?
TIA
