A useful trick
Using COMPUTE to generate groups
• Instead of using IF or DO IF… END IF…
• Use compute and recode
• Check frequencies• Run crosstab• Compute newvar=var1*10 + var2• Recode into desired groups
Bloomsbury and Islington Health and Lifestyle survey 1988
freq var v670 v715.
cro v715 by v670.
Check frequencies and run a crosstab with:

Another useful trick
Using COMPUTE to recode
• To reverse values on items in a scale• Add 1 to the highest code value• Subtract the item value from this figure
• eg: Agree – Disagree scale coded 1-5• Subtracting the item value from 6 reverses it
And one more
Using MEANS to get %
• Choose a value or values to investigate
• Recode these to 100 and everything else to zero
• Run MEANS
• The figures are percentages and the row totals are the base n
…and now
