At the bottom of SPSS, there are options to look at the data in Data View or in Variable View. I clicked on Variable View to name my variables.

The first column was now named SubjectNo, so I typed the list of subject numbers from 1 to 96 (1 number per row) for the number of "participants" in this study. I go back to Variable View and named row 2 as GroupNo. Under the GroupNo column, within Data View, I typed 1’s in rows 1 thru 48 and typed 2’s in rows 49-96. Group 1 was high need for cognition and group 2 was low need for cognition. I labeled the next 45 rows under GroupNO, in the Variable View, as the different item numbers: Item#1 thru Item#45. In all there was a total of 47 rows in the Variable View and 47 columns in the Data View. I clicked back into random.org and highlighted all 4,320 integers not missing any and right clicked for a menu to pop up. In this menu I clicked COPY, then I went back to the SPSS datasheet in the Data View. Under the column labeled Item#1, I clicked on the cell in row 1 and right clicked for the Paste option. All 4,320 integers were placed correctly in the columns, Item#1-Item#45 in 96
