Analysis of Data

Parametric analysis is used to evaluate a range of values for an intervention (independent variable).  For example, if you were determining the range of values for "time out" that are most effective.  You would conduct a parametric analysis…

3 Conditioned Motivating Operations – CMOs

What are conditioned motivating operations (CMOs)?  First we need to discuss motivating operations (MOs).  MOs  or sometimes called establishing operation (EOs) refers to a state that changes the value of consequences and elevates their…
