Hello everyone.

I’m struggling with a experimental design. I have an alternative C, that has 4 attributes (X1, X2, X3, X4) with (2, 3, 4 and 3) levels respectively.

What I want is that respondents rate the alternative according to different scenarios of this alternatives attributes.

Something like this:

ESCENARIO 1: rate from 1 to 5 (consider 1 is the lowest and 5 the hihghest score) the comfort of the bus service according to the following attributes:

  • Spacious seats
  • Tv Available
  • Food available and water available
  • Big windows

1__ 2__ 3__ 4__ 5__

ESCENARIO 2: rate from 1 to 5 (consider 1 is the lowest and 5 the hihghest score) the comfort of the bus service according to the following attributes:

  • Spacious seats
  • No Tv Available
  • Just water available
  • Med sized windows

1__ 2__ 3__ 4__ 5__

How can I do this experimental design, on spss or other software?
