Question: Under the Rasch model (i.e., mdl

Under the Rasch model (i.e., mdl <- 1), set the following ability bounds:

Group 1—The lower bound is 3, and the upper bound is 1.

Group 2—The lower bound is C1, and the upper bound is C3.

Study the resulting display screens. Then try:

Group 1—The lower bound is 2, and the upper bound is C1.

Group 2—The lower bound is 1, and the upper bound is C2.
