I have conducted a tensile test on five specimens. I intend to do a linear regression for every set of data and get a value for the slope (modulus of elasticity) and its error by finding the standard deviation (using LINEST function on excel) of the slope.(adsbygoogle = window.adsbygoogle || []).push({});

I will now end up with 5 slope values and 5 errors. I will then find the average of 5 slopes, but, how can I find the 'average' of the 5 errors to finally obtain one value for the modulus of elasticity and one error?

Thanks in advance
