Exam 10: Quasi-Experimental Design

The most commonly used quasi-experimental design is the regression-discontinuity design.

What design is sometimes referred to as a dry run quasi-experimental design because it simulates what would happen were there no effect of the treatment?

A regression-discontinuity design is particularly attractive when ____.

In its simple form,the _______________ design is very weak with respect to internal validity.

The _______________ design is particularly useful in community-based research,because only one unit receives the intervention.

In what type of design are the people who receive the pretest are not the same as the people who take the posttest?

The degree of correspondence between two data items is referred to as _______________.

​Figure TB 10-14 -Consider the accompanying figure,illustrating the regression discontinuity design.What is shown by C?

A group,comparable to the program group,that did not receive the program,is called a(n)_______________ group.

​Narrative 10-1 -Daycare Center - Part I Ken studies literacy and is particularly concerned about children who lag in reading readiness.He has developed a reading readiness program that can easily be implemented by day care providers in group settings,and has selected two day cares in demographically similar neighborhoods.He starts by giving a reading readiness to all of the three- and four-year-olds in both day care centers.  Figure TB 10-11 -Ken decides to implement his intervention at one daycare but not the other,and after the intervention is complete,he administers the reading readiness test again to both groups of children.His results are shown in the accompanying figure.This figure most suggests the existence of a(n)____ threat.

It is possible to mitigate the non-equivalency of groups in the NEGD by ____.

​Narrative 10-1 -Daycare Center - Part I Ken studies literacy and is particularly concerned about children who lag in reading readiness.He has developed a reading readiness program that can easily be implemented by day care providers in group settings,and has selected two day cares in demographically similar neighborhoods.He starts by giving a reading readiness to all of the three- and four-year-olds in both day care centers.  Figure TB 10-11 -Ken decides to implement his intervention at one daycare but not the other,and after the intervention is complete,he administers the reading readiness test again to both groups of children.His results are shown in the accompanying figure.When Ken talks to reading specialists,he learns that children often progress slowly at first,but when their readiness skills reach a certain point,they seem to take off.Thus children who started at a higher level,like those in his intervention group,may improve faster than children who start off at a lower level,like his comparison group.Given this,it is possible that Ken's results reflect not his intervention,but rather,____ effects.

In the _______________ design,the pretest is collected after the program is given.

In the archived proxy-pretest design,the pretest is based on ____.

With respect to internal validity,quasi-experiments often appear to be inferior to randomized experiments.

In experimental design notation,the letter C stands for ____.

Figure TB 10-2 0 X 0 N 0 0 -What design is shown in the accompanying figure?

Describe the two forms of the proxy-pretest design.

Describe the pattern-matching NEDV design.

A two-group design in two phases defined by three waves of measurement is a ____ design.
