# 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.
- (optional) Enter a seed for the random number generator in the Random Generator Seed: text box.
