Sampling allows you to pick data from a source table (population) to fill a target table. The sampling can be random or in a periodic basis, as well as with or without sample replacement in the source table.

note

El muestreo se efectúa por filas. Esto quiere decir que los datos muestreados abarcarán toda la fila de la tabla de origen y se copiarán en una fila de la tabla de destino.


Datos

Intervalo de entrada: la referencia al área que contiene los datos que se analizarán.

Resultados en: la referencia de la celda en la esquina superior izquierda del intervalo donde los resultados se mostrarán.

Método de muestreo

Aleatorio

Picks exactly Sample Size lines of the source table in a random way.

Tamaño de muestra

Number of lines sampled from the source table. The Sample size is limited to the population size for all sampling methods without replacement.

With replacement

When checked, put back samples in population (source table) after draw. A sample can be drawn more than once and therefore a larger sample size than population is possible. This option is mutually exclusive with Keep order. When unchecked, a sample drawn is not put back to the population and sample size is limited to population size.

Mantener orden

When checked, samples are drawn in order of population data. Samples are not put back to the population (exclusive with With replacement). This option is automatically checked for Periodic sampling. When unchecked, samples are drawn in random order.

Periódico

Picks lines in a pace defined by Period.

Período

The number of lines to skip periodically when sampling. The Period is limited to the population size.
