## Question

How do I create a sum of different variables in SPSS for Windows?

For example,

V1 V2 V3 V4 SUM

2 8 12 3 25

## Answer

Use SUM function to sum variables in SPSS

e.g

Transform / Compute

Sum = SUM(v1,v2,v3,v4)

The Syntax for this would be:

COMPUTE sum = SUM(v1,v2,v3,v4) .

EXECUTE .

You can also do the following if you have more variables:

COMPUTE sum_all=SUM(v1 TO v102).

EXECUTE.

If you don't use the SUM function and instead just use:

SUM = V1 + V2 + V3 + V4

The resulting SUM variable will be a system missing value IF there are any system missings in any of the summed variables (v1, v2, v3 or v4
