descriptive designs
Descriptive correlational
Predictive
Model testing
correlational designs
One-group post-test only
Post-test only with nonequivalent groups
One group pretest- post-test
pre experimental designs
Nonequivalent control group
Untreated control group with pretest and post-test
Removed treatment with the pretest and post-test
Reversed-treatment nonequivalent control group
with the pretest and post-test
quasi experimental designs
Pretest-post-test control group Post-test only control group Randomized block Factorial Nested Crossover or counterbalanced Randomized clinical trials
experimental designs
what level of evidence is non experimental design
level 4 or level 6
non experimental design questions
“what is the relationship…” – Level IV
“what is or what are…” – Level VI
Level VI evidence
Used when little is known about a topic
Collect data about single variables; no relationships between/among variables are tested
No treatment/manipulation/intervention by the investigator
Terms exploratory, descriptive, or survey may be used
Non-experimental Descriptive Designs
Level IV evidence Usually something is known about the study variables (at level VI) No treatment/manipulation/intervention by the investigator Used to (C A R P)
Non-experimental Correlational Designs
what is CARP
correlation, association, relationship, prediction
what are correlational designs concerned about
nature of the relationship (positive, negative, or inverse)
magnitude (small, moderate, large) of the relationship (correlation or association)
Also level IV evidence
Used to test complex theoretical relationships
model testing designs
types of analysis
Linear regression
Structural equation modeling
Path analysis
data are collected in present or future time
prospective designs
