I am going to collect data for a 2*2 factorial experiment. I am looking for free survey websites in which there are options for randomizing stimuli before showing the questionnaire to the participants. Some colleagues say that websites like Conjointly or PsycoPro might be useful in this matter. Do you know any usable easy-to-use website for doing this experiment?
Hello and good day!
As could be seen in the attached PLS graph, I am trying to construct a manifest variable namely PPB (Privacy Protecting Behavior). The data we gathered for this variable has been binary (7 items) taken from the settings of the social media users and not from the survey. As I searched the literature on PLS, we can use almost all data types in our model. However, I failed to understand the mechanism underlying the drawing of this variable. In the Lavaan package of R and Amos as well, it is possible to draw manifests as rectangles having no circular shape.
My specific question is how we should treat manifest variables when drawing a model in the SmartPLS? Hair et al (2019) showed that we can use PLS for measuring binary manifest variables as outputs. I would be really grateful if you let me know how I can overcome this challenge. I searched a lot on the internet, but there was no specific answer, especially on drawing the manifest variables.
