An Independent Group/ between-subjects design differs from a within-subjects design in that in a between-subjects design :-
Between subjects (or Between group) study design: Each subject is exposed to a single user interface only, as different subjects test each condition. Internal subject (or iterative measurement) The same subject tests all conditions (that is, all user interfaces).
Between subjects or inter-group designs, each participant experiences only one condition and compares the group differences between participants with different conditions. This is the opposite of the in-subject design where each participant experiences each condition.
