Read Ihno's data into your statistical software package. For those not using the Statistical Package for the Social Sciences (SPSS), we have provided the data in two convenient formats: a tab-delimited text file and an Excel spreadsheet (Microsoft Office 2007). For the convenience of SPSS users, we have also included the data as an SPSS.sav file, though your instructor may want you to know how to read text or Excel files into SPSS.
