 Lvl Code Display Definition 0 _ObservationMethodAggregate observation method aggregate Provides additional detail about the aggregation methods used to compute the aggregated values for an observation. This is an abstract code. 1 AVERAGE average Average of non-null values in the referenced set of values 1 COUNT count Count of non-null values in the referenced set of values 1 MAX maxima Largest of all non-null values in the referenced set of values. 1 MEDIAN median The median of all non-null values in the referenced set of values. 1 MIN minima Smallest of all non-null values in the referenced set of values. 1 MODE mode The most common value of all non-null values in the referenced set of values. 1 STDEV.P population standard deviation Standard Deviation of the values in the referenced set of values, computed over the population. 1 STDEV.S sample standard deviation Standard Deviation of the values in the referenced set of values, computed over a sample of the population. 1 SUM sum Sum of non-null values in the referenced set of values 1 VARIANCE.P population variance Variance of the values in the referenced set of values, computed over the population. 1 VARIANCE.S sample variance Variance of the values in the referenced set of values, computed over a sample of the population.
