3 is the standard deviation. The method assumes that the random errors follow a normal distribution, which may not always be true.
Standard Deviation Uncertainty in Real World Application
Translating this statistic into an uncertainty value essentially means stating that the true value likely lies within a specific interval centered on the average, with the width of that interval determined by the standard deviation. If a set of repeated measurements has a small standard deviation, the values are close together, suggesting high precision.
Connecting Spread to Confidence At its core, the standard deviation measures how tightly values cluster around the mean in a dataset. The standard uncertainty of the mean, however, describes the precision of the average itself and is calculated by dividing the standard deviation by the square root of the number of measurements.

This approach is not arbitrary; it is rooted in the properties of the normal distribution, where a specific percentage of data falls within defined ranges around the mean. The standard deviation describes the variability of the individual measurements.
