Re: Entering Ranking Questions in SPSS and Conjoint Analysis

You can change to multiple dichotomies after you have entered and proofread the data.

Hi Art,

Many thanks for the clarification. Our professor has mentioned that for the conjoint analysis, we need to strip down the components of each concept (there are 6 concepts, with 4 components each) in order to run an analysis and see if individual components of the concept (being dummy variables) are affected by other independent variables. 

The second approach you mentioned sounds good, I had no ideas you could enter non-numeric data into SPSS.

Many thanks. I may drop a couple of queries your way later, many thanks for clarifying this.

You just need 6 variables.
depending how your data gathering instrument is arranged
If the instrument presents the same list of concepts and the respondent
 just puts in 1 to 6. Then just name the 6 variables and enter the rank number. the variables might be apple orange banana cherry pear grapes.
you might enter 2 1 3 6 4 5

If the respondent writes in the concepts in their subjective rank order then enter the data as a multiple response variable.
variables rankedfruit1 to rankedfruit6.
you might enter
grapes banana pear apple cherry orange

Be very sure that you proofread you data input with someone or have the data entered by yourself and another person and compare the files.

Hi there,

I磎 doing a project for my MBA course and as part of choosing a conjoint analysis for our project (痛m kicking myself for my ambition!), there磗 a simple ranking question that I want to enter in SPSS. Respondents have to rank 6 different concepts from 1 to 6, 1 being the most preferred and so on.

Currently, I磎 entering the question by creating 6 variables per concept, each variable denoting a ranking for that concept and using a nominal ranking of yes/no for each ranking. So 6 concepts that each receive rankings of 1 to 6 require 36 rows. Is there a simpler way. Apologies if this is a dumb question, but I磎 a bit of an SPSS novice

Also, on the topic of conjoint analysis, I磀 he glad to hook up with any experts in the field and pick their brain on the subject!
