Data > Generate Random Data > Samples from Colum
This utility simulates the process of drawing random samples
from a set of data values with or without replacement.
To use this utility, you must specify a column containing data values
to draw samples from, column name(s) in which samples will be stored,
whether the samples are replaced after being chosen, and the sample size.
Providing a seed for the random number generator is optional.
Dialog Inputs
- Select the column containing data values to draw samples from
in the Samples from Column: drop-down menu.
- In the Store Samples in: text field, enter the
column names in which random samples will be stored, separated
by spaces. For a continuous range of columns, specify using
the first column, a dash, and the last column (e.g. C1-C30).
- Select the Sample With Replacement check box to sample
with replacement. Deselect to sample without replacement.
- In the Number of Samples to Generate: text box,
enter the number of random samples to generate. The sample size
must be no larger than the number of possible data values if sampling
without replacement.

the Random Generator Seed: text box.
