For this assignment, review Questions 1 and 8 on page 268 in the Review Questions section from your text. Then, develop a brief paper responding to these two
questions.
Question 1 asks about the two main exceptions of a quasi-experimental design
being structured similar to an experiment, and Question 8 invites thoughtful
reflection as to why single-case design is considered an experimental research design.
Support your assignment with at least two scholarly resources. In addition to
these specified resources, other appropriate scholarly resources, including
seminal articles, may be included.
Length: 1 page, not including title and reference pages
QUESTION 1
“Define and identify a quasi-experiment and a quasi-independent variable.
A quasi-experimental research design is structured similar to an experiment, except that this design lacks random assignment, includes a preexisting factor (i.e., a variable that is not manipulated), or does not include a comparison/control group. A quasi-independent variable is a preexisting variable that is often a characteristic inherent to an individual, which differentiates the groups or conditions being compared in a research study. Because the levels of the variable are preexisting, it is not possible to randomly assign participants to groups.

QUESTION 1
“A quasi-experimental research design is structured similar to an
experiment, with what two exceptions?”
QUESTION 8
“Identify in a graph the stability and magnitude of a dependent measure, and explain how each is related to the internal validity of a single-case design.
The stability of a measure is the consistency in the pattern of change in a dependent measure in each phase of a design. The more stable or consistent changes in a dependent measure are in each phase, the higher the internal validity of a research design. The magnitude of change in a measure is the size of the change in a
dependent measure observed between phases of a design. A
measure can have a change in level or a change in trend. The larger the magnitude of change, the greater the internal validity of a research design.”
QUESTION 8
“Why is the single-case design regarded as an experimental research design?”
