    3. Cthey both have stronger utility
    4. Dthey both require random assignment to groups
  2. 2100 clients with GAD split across 2 clinics, 50 doing mindfulness, and 50 in a control, with all participants completing the STAI before and after is an example of a
    1. Apost test non-equivalence design
    2. Bmixed non equivalence design
    3. Cpost test equivalence design
    4. Dmixed equivalence design
  3. 3The following is not true about QEDs

    2. BThey use manual assignment
    3. CThey have all the same limitations as a TED, false dichotomy, maturation, etc
    4. DThey have no theoretical or practical limitations
  4. 4In a QED, the bigger the difference between groups, the more likely that
    1. AGroup equivalence is an issue
    2. BThe difference is genuine
    3. CThe difference is due to the difference within the groups
