Exam 7: Nonexperimental Approachesdesigns

Having more than four groups is common, regardless of the type of variable that is used.

The addition of a placebo control group to a research study with two experimental conditions:

An investigator is interested in the relationship between self-concept (measured from 1-10) and anxiety (measured from 1-100). The research approach used in this situation is the:

Most published research studies include only one of the types of research approaches.

The comparative research approach is sometimes called ex-post-facto.

Considering the five quantitative approaches, how do you determine which approach to use?

A researcher reported that 20% of the males in her study had high anxiety levels before taking a test. The research approach used in this situation is the:

It is up to the researcher whether a study is considered to be comparative or associational.

When determining if a study has been designed using the comparative research approach, one should be sure:

Most research studies have at least some descriptive questions.

Attribute independent variables are manipulated by the researcher.

Random assignment of participants to groups by the investigator is commonly used with all the research approaches.

The descriptive research approach is restricted to studies with:

Can a single study have more than one approach?

The following is a key element for the descriptive research approach:

When using the descriptive research approach, there is no independent variable.

When using the comparative research approach, one can meet the criteria for attributing causality.

How does the comparative research approach differ from the randomized experimental and quasi-experimental approaches?

Qualitative research approaches are most similar to the:

What type of independent variable must be used with a nonexperimental approach?
