- Parameters
data (array-like) -- The data for which to take the measure of central tendency.
- Returns
central_tendencies (
dict
ofstr
-> numeric) -- The measures of central tendency, ordered by their distance from the geometric meandian. Its keys are:"gmnd" : geometric meandian (always first)
"arithmetic" : arithmetic mean
"geometric" : geometric mean
"median" : median
