They should make it more clear by staing the numbers on the instructions though… because its interpretable to me.
I really thought 1 is worst and 6 is best. And sometimes some surveys go that way. 1 can mean the worse and 6 the best while other surveys can be vice versa.
Let’s just say if there’s any chance of ambiguity or misinterpretation, immediate action should be done to correct it.
