Outline
• Available packages
• Layout
• Entering data
• Data analysis
Entering Data
• Can open Excel files in StatsDirect/SPSS but won’t retain formulae.
• If starting from scratch, double click on grey headings to change titles.
• If opening Excel file in StatsDirect, titles take up the first row. In SPSS, they become the grey headers.
• Make sure one variable per column.
• Convert dates/times.
• Both packages only deal in numbers, text just for reference so could need coding.
Missing Data
• StatsDirect treats a blank cell as missing data, but also recognises a ‘*’.
• Better to use a ‘*’.
• SPSS recognises a ‘.’.
• Better to use codes, which can be established in ‘Variable View’.
• E.g., for the variable systolic BP, ‘888’ when missing due to refusal to disclose, ‘999’ when missing due to death, etc.
Anything below this line requires having a dataset and selecting columns from the worksheet.
When performing analyses using the worksheet prompts will appear at each stage specific to type of analysis:
