Week 6 part 1

1. 1Quasi-experimental designs (QEDs) are basically just True experimental designs (TEDs) because

   1. Athey both involve group comparison and significance testing
   2. Bthey both have weaker internal validity
   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

   1. AThey are more ethical than TEDs
   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
   4. Dthe true difference is unable to be determined
5. 5In natural group design (NG) the

   1. Agroups become the IV
   2. Bresults are often highly relevant
   3. Cdesign is ethical
   4. Dall of the above
6. 6TEDs, QEDs, and NG's are all

   1. AAll of the above
   2. BExperiments
   3. Chave high efficacy
   4. DHave high utility
7. 7A way to reduce the chance of non equivalence between groups is

   1. Apre assessment
   2. Bmatching
   3. CRandom assignment
   4. DManual assignment
8. 8Regression discontinuity design (RDD) refers is another approach to reduce non equivalence between groups. It entails

   1. Ainitiating treatment using a pre-determined cut off point
   2. BSorting groups by observable characteristics such as ethnicity, age, or gender
   3. CRandom assignment to treatment groups
   4. DAll of the above
9. 9In an RDD, if the treatment is effective the line of best fit should

   1. AIndicate a positive linear relationship
   2. BIndicate a negative linear relationship
   3. Cbreak at the cut off point
   4. Dchange direction at the cut off point
