Q: When using a anchor-based vertical ask string, is there research on whether the Other: $____ option is best at the top of string or at the bottom.

Example:
Other: $_____
$600
$300
$150
$75

or
$600
$300
$150
$75
Other: $_____

 

I’m not aware of anyone testing these specific layouts so I don’t have any data to share. But the anchoring effect takes place when people see an influential number first. So, I’d expect an anchoring effect to appear with the second layout, when you start with the $600, which gets imprinted on people’s mind.

However, it might be worth testing this yourself. There’s a chance that people might glance at the first and second rows together in which case an anchoring effect might occur there too.
