Reproducibility of experiment

Dear list,

I have an experiment that I have run 10 times in order to find out its 
reproducibility. I wonder if there is any function that I can use for 
obtaining a significance value of reproducibility or agreement of 
measurements. I thought of coefficient of variation but, as far as I 
know, I would have to set a threshold for saying the experiment is not 
reproducible. Any pointers to something more "objective" would be very 
helpful.

Thanks

David
