First, the observations are sorted in increasing order. For an odd number of observations, the median is the middle value of the sorted data. For an even number of observations, the median is the average of the two middle values. median calculation variance calculation standard deviation calculation interquartile-range calculation skewness calculation kurtosis calculation planned process entity occurrent process processual_entity definition editor editor note definition source curation status preferred term definition relates a class to a property where instances of the class make sense as subjects of the property relates a class to a property where instances of the class make sense as objects of the property relates a class to a property where some instances of the class may make sense as subjects of the property relates a class to a property where some instances of the class may make sense as objects of the property has_input is_input_of has_output is_realized_as is_reagent_in is_realization_of utilizes_reagent is_instrument_for is_output_of utilizes_instrument adjacent_to agent_in contained_in contains has_agent has_integral_part has_part has_participant has_proper_part integral_part_of part_of participates_in preceded_by precedes proper_part_of relationship metadata complete
