Non Experiments
Non-Experimental Designs:
Includes:
Case studies
Naturalistic observations
Interview studies
Focus groups
surveys/questionnaires
Questionnaires
Can also be called cross-sectional studies
Do not allocate participants to different groups
Are a sample of the population
Cross-sectional Design
Passive Designs - the important stage of planning and critically thinking about the
research question
Associational Studies - only emphasises assumed result before the data is collected
Correlational Studies - a statistical procedure and not a true design
Population sampled should be randomly selected if possible
Choice of the population is important
Application
When the question needs to study to pre-existing populations
Early in the examination to find relationships among constructs
When it is not ethically or practically possible to conduct experiments
When combining multiple variables
Studying the relationship between constructs
Refining tests
Scale Development
Step 1:
Development of items
Statements, problems that capture an aspect of the construct of the scale
Step 2:
Coherency through factor analysis
Construct validity
Divergent validity

Associational studies - only emphasises assumed result before the data is collected. Correlational studies - a statistical procedure and not a true design. Population sampled should be randomly selected if possible. When the question needs to study to pre-existing populations. Early in the examination to find relationships among constructs. When it is not ethically or practically possible to conduct experiments. Statements, problems that capture an aspect of the construct of the scale.
