Complete the following steps to specify the data to sample and the sampling method:
(Optional) In Base for random number generator, you can specify the starting point for the random number generator by entering an integer that is greater than or equal to 1. When you use the same base number, you get the same sample.
For example, a professor samples 40 rows from a column for use in a classroom exercise. The professor and students each set the base to 1 to generate the same data and thus, the same analysis results.
