The Research Process
1. Research Idea: Topic library research hypothesis
2. Define and measure variables: must be reliable and valid
3. Identify participants or subjects: which ones? How many? Ethics!!!
4. Determine which strategy will best answer question: experimental, quasi-experimental, correlational, or
descriptive study (consider limitations of each)
5. Choose specific research design: between or within subjects? Single subject? Factorial design?
6. Do the study (collect your data)
7. Analyze your data (descriptive and inferential statistics)
8. Write paper (APA ; remember ethical considerations)
9. Assess original idea: alter, refine, expand… (Gravetter & Forzano, 2009, p. 26)
Elements of a Good Hypothesis
Logical/ Testable/ Refutable/ Positive
1. Logical Hypothesis
Fou n d ed in theory(framework that ex plains curr ent d ata/ stu dies that h ave b e e n co n d u cted)
develop ed from p ast stu d y result s
Premise 1: Aca demic succ e s s is hig hly v alued an d respe c ted in society (at le a st by p arents an d te a
Premise 2: Being v alued and respe c ted by others co n tribu tes to high self-este e m.

(Gravet t er & Forz a n o, 2 0 0 9 , p. 2 7)

Sh o uld b e able to o b serve and me a sure all imp ortant variables
(c a nnot b e imaginary, hy po thetic al, or b eli ef b ased (i.e. GOD/LOVE)
3. Refutable Hypothesis
www.notesolution.com
Must be able to falsify predictions t hat stem from hypothesis
Are the following hypotheses suitable?
The more sins a person com mits, the less likely she is going to heaven (X Not testable)
Abortion is morally wrong (X Not testable/ refutable)
If people could fly, there would be substantially fewer cases of depression (X Not testable)
The human mind emits thought waves that influence other people, but cannot be measured or
recorded in any way (X Not testable)
(Gravetter & Forzano, 2009, p. 28)
4.Positive Hypothesis
Should state that something (usually a relationship between two variables) exists (premise o
hypothesis testing is that we assume it doesnt exist)
Choose the positive hypotheses
There is no relationship between stress and health (X positive)
A negative relationship exists between stress and health (Positive!)
There is a difference between the language abilities of 4 year old girls and 4 year old boys (
The new treatment does not affect anxiety levels (X positive)
Hypothesis to Predictions
HYPOTHESIS: The dark and dreary environment during the winter leads to depression
