1. Increasing______ variable causes an increase in _______ variable
2. Increasing ______ variable causes a decrease in _________ variable.
Of course, more complicated hypotheses are appreciated. For example, a great hypothesis might be in the form
The more _____ variable, the (less/more)_____ variable, depending on
|Does your hypothesis involve psychological variables? (Please do not hypothesize that leaves will turn green.)|| |
Is your predictor variable psychological? Try to avoid physiological manipulations such as drugs
(e.g., caffeine). |
you should probably avoid manipulations like eating breakfast
and sleep deprivation.
Are you predicting that participants differing on one variable
will also differ on another? ||
| Can your variables be objectively measured |
|Can the hypothesis be tested without violating |
APA's ethical standards?
|Is there a reasonable chance that your hypothesis will be wrong?
Your hypothesis should be somewhat risky: It should not be an already established fact.
|Can you produce sound reasons why the |
hypothesis might be supported--
and do these reasons come from logic, theory, or past research?
If so, please outline those reasons on the back of this sheet.
|If the results turn out as you expect, |
will there be implications for theory, practice, or future research?
|* Are you predicting that changing one variable will cause an effect on another variable?|
|* Can you manipulate your predictor variable? |
That is, does it involve instructions, stimuli, or treatments that you can give to one set of participants, but not to another?
| **Do you have a moderator variable? |
The moderator variable would intensify, weaken, or reverse the relationship between two other variables.
