Summary functions are used in Dashboard tiles to determine how multiple values are aggregated and summarised into a single value, for displaying as a visualisation like a bar on a chart.
Following is a list of available summary functions and an explanation on how they'll aggregate the data.
Counts the number of values.
Counts the number of distinct values.
The sum of the values.
The smallest value.
The largest value.
The average of the values.
An estimate of the standard deviation of a population where the sample is a subset of the entire population.
The standard deviation of a population where the population is the entire data to be summarised.
An estimate of the variance of a population where the sample is a subset of the entire population.
The variance of a population where the population is the entire data to be summarised.
The median of the values. A median is the number separating the higher half of a value range from the lower half.
The mode of the values. A mode is the value that is repeated more often than any other.
