Numeric by script (AskiaAnalyse)

This feature allows you to create a numeric variable using the functions of AskiaScript. You can use it to:

• recode a variable with responses into a numeric variable;
• route impossible values of a numeric question;
• carry out calculations (addition, division, multiplication, etc.);
• determine the number of responses given to a multiple-coded closed question.

To access this feature, in the edit menu select create a variable... and select numeric by script. Drag individual questions from the question list in the left-hand pane into the script window, and make use of the functions in the contextual (right-click) menu. Enter the name of the new variable in the caption box.

Example A

If we wanted to select the number of answers given to a multi-coded question, in AskiaAnalyse we might enter:
SIZE(??Q1??)

Example B

If we wanted to transform a response value into a non-answer, we might enter:
ON(??Note??=99, DK, ??Note??)

Example C

Suppose we want to assign a value to each item of the question Q1 Satisfaction, as follows:

• Totally satisfied (value to assign 10)
• Satisfied (value to assign 7)
• Almost satisfied (value to assign 4)
• Not satisfied (value to assign 0)

We would enter:

On(??Q1??=1,10,7,4,0)

We would then validate our script.

Example D

If we wanted to remove the value 99 from the numeric variable Q1, with values from 1 to 99, we would enter:

On(??Q1??= 99,NR,??Q1??)

Example E

If we wanted to carry out a calculation on two numerical variables: Q1 + Q2, we might enter the following:

• Sum: CVDKNA(??Q1??) + CVDKNA (??Q2??)
  Note that the function CVDKNA allows you to transform the non-responses or not-askeds to 0.

• Multiply: CVDKNA(??Q1??) * CVDKNA(??Q2??)

• Divide: CVDKNA(??Q1??) / CVDKNA(??Q2??)

Example F

If we wanted to find the middle number of the responses given to Q1 (a multi-coded question), we might enter:

SIZE(??Q1??)
