Using your report that contains the complete set of cases:

  1. Add row to the right of the Column of numbers you want to sample and name it whatever you want to call it (i.e. Random Sample). The example here contains 45 unique visit numbers.
  2. In B2 type in the formula =RAND() and then press enter to assign a random number.
  3. Double click on the little box in the lower right corner of the B2 cell. This will repeat the function for all the rows in your report. Make sure there are no blank rows. See sample on Page 2.

4. Key step – replace the function with the value a. Go back to the top of column B and left click to highlight the entire column. b. With column B highlighted do Ctrl+C (or right click and select Copy). c. Click on the bottom portion of Paste to bring up the paste options. Select Paste Values. The numbers won’t change, but this step is still necessary. Depending on what version you are working in this option might look different. The key is to copy and select “Past Values”. This replaces the function with the actual value. If this isn’t done, whenever anything changes on the page it will generate a new number.
