Data > Code > Numeric to Text



More Complex Coding

Suppose we want to compare men, women & children Lets begin by coding males and females

Step 1: Extract Mr, Miss, Mrs, etc.

Step 2: Create table for Mr=male, Miss=female, etc.



Coding Many Values

1. Choose Stat > Tables > Tally

Individual Variables > Store results

2. Manually create a 2ndcolumn for the

new values

3. Choose Data > Code > Use

Conversion Table



Coding by Condition

Step 3: Calc > Calculator to code using bothGender & Age

If Age>=18 MWC = Gender (male or female)

Else MWC = child



Now were ready to explore the data
