SPSS Conjoint Analysis

[E. Bernardo]

Dear SPSS users,

Can we use Likert scale format in measuring the preference of respondents on each profile/card, rather than ranking?

Thank you.

Yes, it is possible. In the conjoint syntax you can specify that evaluation on scale was used instead of ranking.

CONJOINT [PLAN={* }]
{file}
[/DATA={* }]
{file}
/{SEQUENCE}=varlist
{RANK }
{SCORE } /* use score here  */ ....

Yes, in the DATA subcommand it is possible to define the data as being a
'SCORE'

From the syntax reference manual: "Each data point is a preference score
assigned to the profiles, starting with the score of profile 1, then the score
of profile 2, and so on. These types of data might be generated, for example,
by asking subjects to use a Likert scale to assign a score to each profile or
by asking subjects to assign a number from 1 to 100 to show how much they like
the profile. A higher score implies greater preference."
