In my lab report, I average the values of the index of refraction of a prism and I calculated the average uncertainty from the uncertainties in all those measurements. My questions is my final value is 1.585 +/- 0.006

I'm assuming my uncertainty should be rounded to 0.01 but does that mean my value should be rounded to 1.59 or 1.60?
