Remember that your research design and methods

should be determined by your research question

Can a traditional experimental design be used to conduct your study

or is a variation from the traditional design necessary.

recognize and evaluate main effects and

interactions in factorial designs

Be wary of using complex factorial designs that result in

numerous main effects and interactions

consider the temporal ordering of your variables

(i.e., the hypothesized cause must precede the hypothesized effect)

consider designing a few discrete experiments that build on one another,

rather than conducting a single large experiment with many factors

Ensure the internal validity of your design through random

assignment of participants to your different experimental conditions

If you have a small sample size, quasi-random assignment to

guarantee distribution of participants across key characteristics may be necessary.

Ensure that any control group in your design is equivalent to

the intervention group on all possible dimensions other than the intervention itself

Assess whether your topic can be best examined

through a between-group or within-group design

decisions should be based on both pragmatic considerations and

what is likely to give you the most accurate results.

use strategies to control for confounds as part of the design or

account for them in analyzing your results

Develop a plan to address ethical limitations

and protect the rights of all of your participants.

Practical Tips for Variations on Experimental Designs

Term	Definition
Remember that your research design and methods	should be determined by your research question
Can a traditional experimental design be used to conduct your study	or is a variation from the traditional design necessary.
recognize and evaluate main effects and	interactions in factorial designs
Evaluating more than a three-way interaction effect	can be quite difficult
Be wary of using complex factorial designs that result in	numerous main effects and interactions
choose the levels of your independent variable with	experimental control in mind
consider the temporal ordering of your variables	(i.e., the hypothesized cause must precede the hypothesized effect)
consider designing a few discrete experiments that build on one another,	rather than conducting a single large experiment with many factors
Ensure the internal validity of your design through random	assignment of participants to your different experimental conditions
If you have a small sample size, quasi-random assignment to	guarantee distribution of participants across key characteristics may be necessary.
Ensure that any control group in your design is equivalent to	the intervention group on all possible dimensions other than the intervention itself
Assess whether your topic can be best examined	through a between-group or within-group design
decisions should be based on both pragmatic considerations and	what is likely to give you the most accurate results.
use strategies to control for confounds as part of the design or	account for them in analyzing your results
Develop a plan to address ethical limitations	and protect the rights of all of your participants.
