This tutorial covers some obvious and some less obvious functions for editing numeric variables. You can follow along with this tutorial by downloading and opening hospital.sav. They syntax we’ll use can be copy-pasted or downloaded here. Specifying User Missing Values This tutorial will only use the last 2 variables in the data.* Before doing anything else, we first specify […]
String variables are variables that hold zero or more characters such as letters, numbers, spaces, commas and many more. You can’t use numeric functions such as addition or subtraction on string variables. You can, however, extract one or more characters (a substring) from them, glue them together (concatenate) and a couple of other functions. Like so, working […]
Recoding both string and numeric variables in SPSS is usually done with RECODE. Doing so with syntax is way faster than with the menu, especially if you want to recode many variables at once. Note that you’ll often want to apply or adjust some value labels after recoding.Alternatively, string variables can be recoded into numeric variables with AUTORECODE. Doing […]
Working with string variables in SPSS is pretty straightforward if one masters some basic string functions. This tutorial will quickly walk you through the important ones. SPSS Main String Functions CHAR.SUBSTR (substring) – Extract character(s) from string CONCAT (concatenate) – Combine strings CHAR.INDEX – Find first occurrence of character(s) in string CHAR.RINDEX (right index) – Find last occurrence of character(s) in […]
