Module 1 - Quasi-experimental Design Flashcards
Used when researchers cannot obtain results using true experimental methods.
Quasi-experimental Design
TRUE or FALSE:
In Quasi-experimental design, the researcher cannot randomly assign units or participants to conditions
TRUE
“Resembles” experimental research.
Quasi-experimental Design
TRUE or FALSE
In Quasi-experimental design, they cannot generally control or manipulate the independent variable,
TRUE
TRUE or FALSE
In Quasi-experimental design, they cannot eliminate the influence of extraneous variables.
TRUE
Although the term “quasi-experiment” includes the word “experiment,” quasi-experimental designs lead to ____ claims, not causation claims.
Association
Quasi-experimental designs are helpful when assigning participants to conditions _____
Randomly
manipulating the independent variable is ____, ____, or _____.
- impractical
- impossible
- unethical
TRUE or FALSE
Quasi-experimental designs differ from correlational designs because they include some attempts to create equivalent groups and some attempts to manipulate the independent variable, or both. For this reason, these designs can support a stronger claim about associations between variables.
TRUE
A school interested in testing a new teaching method can only implement it in preexisting classes and cannot randomly assign students.
Practical Constraints
A medical study might not be able to randomly assign participants to a treatment group for an experimental medication when they are already taking a proven drug.
Ethical Concerns
Quasi-experiments cannot exclude all confounding variables when investigating ____ relationships between variables, so we cannot unequivocally establish causation with a quasi-experimental study.
Causal
Quasi-experimental designs include some (but not all) of the elements of ____ observation found in experimental designs, thus eliminating some of the problems with making causal conclusions that are found in correlational designs.
Controlled
A researcher may choose a ____ over an experimental design to gather data in the real world or to gather data about variables that cannot practically or ethically be manipulated.
Quasi-Experimental Design
The most common experimental element missing from quasi-experimental designs is the use of _____ ______.
random assignment
