What do research designs relate to?
|
the question asked
|
|
|
What are the 4 different types of research?
|
-correlational
-descriptive -causal comparative/quasi-experimental -experimental |
|
|
Which 2 types of research are nonexperimental?
|
-correlational
-descriptive |
|
|
What is correlational research?
|
use to examine relationships between 2 variables. It can also be used to predict behavior or performance.
|
|
|
For correlation research, if multiple variables comprise a behavior or attribute, then what kind of analysis can be performed?
|
-multiple regression analysis
|
|
|
What is descriptive research?
|
use to describe the characteristics of a phenomenon
|
|
|
True or false: for descriptive research, the experimenter does not manipulate the independent variable.
|
True
|
|
|
How is descriptive research data expressed?
|
-summary of information (categories, total # of something, % scores, means, SD, etc.)
|
|
|
What are some examples of descriptive research?
|
survey research, case studies, small group studies, longitudinal and cross-sectional studies
|
|
|
Are case studies qualitative or quantitative?
|
qualitative
|
|
|
What is the difference between cross-sectional and longitudinal studies?
|
-cross-sectional: looking at different people for a particular time frame
-longitudinal: look at same sample of people across time |
|
|
What is quasi-experimental/casual comparative research?
|
-compare 2 groups of people and imply
-group assignment and membership is pre-determined by classification of participants (males, females, LD, etc.) |
|
|
What type of research involves "matching"?
|
quasi-experimental/casual comparative
|
|
|
For quasi-experimental/casual comparative research, can you randomly assign participants to a group? Can you randomly select the participants?
|
No; yes
|
|
|
For experimental research, can you randomly assign participants to a group? Can you randomly select participants?
|
Yes; yes
|
|
|
What is "matching"?
|
pairing participants together with the same characteristics (age, gender, grade level)
|
|
|
What is experimental research?
|
a design which allows for a true test of the difference based on cause/effect relationship
|
|
|
How is experimental research set up?
|
-assign participants to a control group and an experimental group
-by using control group, the effect is directly related to the independent variable |
|
|
What is single-subject research design also known as?
|
"N of 1" (recognize that we are talking about a population) or "Small n" (a sample of a population) studies
|
|
|
How participants are involved in single-subject research designs?
|
1-3
|
|
|
Why do we "match"?
|
to eliminate other variables that could affect the outcome/interpretation of the study
|
|
|
True or false: Statistical data has to be performed for single-subject research designs.
|
False; graphic data shows all of the results
|
|
|
What does "A" stand for in single-subject designs?
|
Baseline (no intervention)
|
|
|
What does "B" stand for in single-subject designs?
|
Treatment (if more than one Tx, use B1 or B2)
|
|
|
What does "C" stand for in single-subject designs?
|
sometimes used as a designation for second Tx
|
|
|
What are the important aspects of ABA for single-subject?
|
-allows for unique and "typical" behaviors/patterns to emerge that would be missed if group data were collected
-repeated observations add to the reliability of response -generalization depends on how patterns fit available research in field |
