Properties ¶

Name	Direction	Type	Default	Description
InputWorkspace	Input	TableWorkspace	Mandatory	Input table workspace.
ColumnIndices	Input	long list		Comma separated list of column indices for which statistics will be separated

Description ¶

Calculates mean, median, maximum, minimum and standard deviation for each numerical column of a table workspace.

Usage ¶

Example - Getting statistics of a table workspace.

ws = CreateEmptyTableWorkspace()
ws.addColumn('int', 'a')
ws.addColumn('float', 'b')
ws.addRow([1, 3.2])
ws.addRow([2, 3.4])
ws.addRow([3, 3.6])
ws.addRow([4, 3.8])

stats = StatisticsOfTableWorkspace(ws)

for idx in range(stats.rowCount()):
    stat_name = stats.column('Statistic')[idx]
    stat_value = stats.column('a')[idx]
    print('%s of column \'a\' is %.3f' % (stat_name, stat_value))

Output:

StandardDev of column 'a' is 1.118
Minimum of column 'a' is 1.000
Median of column 'a' is 2.500
Maximum of column 'a' is 4.000
Mean of column 'a' is 2.500
