I found two different products, and for each product, I found a female and a male to sell them in different ways.
1. The respondents needed to answer the same questionnaire twice after the four sellers showing them the two different products.
2. I want to see the moderating effects (different products coded as 0 or 1 variable), but could not see the significant differences when respondents were facing the female or male sellers (coded as 0 or 1 variable as the antecedent) when purchasing two different products.
Specifically, I want to find out, for example, when selling the service products, female seller has greater influence than male seller. However, when selling the normal product, I want to figure out female seller's influence lower than the male seller.
I was wondering whether it was because of the moderator was not correct and I need to find a new moderator or I did not find the right method to run the analysis? I could not really see the influence was reduced.
