How do you Summ variables in SPSS?

To create a new variable in SPSS, use the compute command. You can use this command in many ways: To create a variable called total equal to the sum of variables v1 , v2 , v3 , and v4 , the syntax is: compute total = v1+v2+v3+v4.

Can you rearrange variables in SPSS?

Click Data > Sort Cases. Double-click on the variable(s) you want to sort your data by to move them to the Sort by box. If you are sorting by two or more variables, then the order that the variables appear in the “Sort by” list matters. You can click and drag the variables to reorder them within the Sort by box.

DO If condition in SPSS?

IF is a conditional COMPUTE command whereas DO IF can affect other transformations -such as RECODE or COUNT- as well. If cases meet more than 1 condition, the first condition prevails when using DO IF – ELSE IF. If you use multiple IF commands instead, the last condition met by each case takes effect.

How do I compare two variables in SPSS?

The Compare Means procedure is useful when you want to summarize and compare differences in descriptive statistics across one or more factors, or categorical variables. To open the Compare Means procedure, click Analyze > Compare Means > Means.

How do I count missing values in SPSS?

The if/else if statement allows you to create a chain of if statements. The if statements are evaluated in order until one of the if expressions is true or the end of the if/else if chain is reached. If the end of the if/else if chain is reached without a true expression, no code blocks are executed.

What is the difference between SPSS if and compute?

SPSS IF – Compute a Variable for a Selection of Cases. SPSS IF – A quick tutorial with simple examples. IF is similar to COMPUTE but for a subset of cases only. For example: if(gender = 1) score = sum(q1 to q5).

How do I compute variables in SPSS?

How to use SPSS if VAR1=1?

SPSS will process the DO IF command for this case and say “VAR1=1: true” and go to the COMPUTE command so NEW_VAR=1. The case then falls out of the DO IF structure and SPSS goes to the next case.
