Aggregate Operations

The following operations are available for iterable collections of measurements:

• sum: Sum a collection of measurements.

• min: Find the minimum of a collection of measurements.

• max: Find the maximum of a collection of measurements.

• average: Find the average of a collection of measurements (Uncertainty = \(\Delta x = \frac{x_{max}-x_{min}}{2\sqrt{n}}\)).

All of these operations return a new measurement object.

>>> collection = [M.fromStr('20.23d g'), M.fromStr('13.86d g'), M.fromStr('46.37d g')]
>>> M.sum(collection)
80.46 +/- 0.03 g
>>> M.min(collection)
13.86 +/- 0.01 g
>>> M.max(collection)
46.37 +/- 0.01 g
>>> M.average(collection)
26.82 +/- 9.38 g
