What Are They?• A research design in which the
researcher measures or observes subjects or variables without attempting to introduce a treatment.

How Could I Use NEQDs for Program Evaluation?
Explore the relationship(s) between two or more variables
or elements of a program.
Use the knowledge of two correlated variables to inform
practice or program revisions and implementation.
NEQDs can require the usage of an underling theory to
explain or interpret correlations. Control variables are then employed to further rule out the effects of
extraneous variables on the variables that a theory may have causally
linked.

What if We Want More?
What tools are available to analyze systems with multiple (and possible
causal) relationships?

Advantages
• Allows for:– the study of independent variables over
which the research cannot have any control.
– the manipulation of variables in theory that cannot often be manipulated in practice.
– the study of variables as they exist.

Disadvantages Determining causality and/or the
direction of causality. Mutual causality Selection bias Spurious Correlations
