I Have a large set of data, but each value was estimated. I need to measure how accurate the estimations are without measuring every point. If I can somehow use statistical sampling or somthing and measure a small percentage of the points then somehow statisticly indicate how accurate the original data set is to determine if I need to measure more points to check it or leave it alone.

What is the scientific method for this?

Thank you much...
