Dear community
I want to set two options in each question. These two options are two tables randomly selected from my ten tables.
For example, ABC represent three bakeries, and A has a production of 800 and a price of 20, and B has a production of 300 and a price of 50.I have ten such tables, each of them are fixed.But in one choice,respondents can only choose between two randomly selected tables for thei favorite ideal bakery.
In addition, the order of the rows in the table is also random. That means for different participants, the row order of price, output in the table needs to be different.
And importantly,I‘ll let them choose many times,how to avoid duplicated matches?
I’ll be soooo grateful if I could get help!
