1. RESEARCH OBJECTIVES OR AIMS: clear, concise, declarative statements
expressed in the present tense to specify foci of the study
2. Hypothesis: A stated relationship between or among variables within a special
population The hypothesis translates the problem and purpose into a clear explana-
tion or prediction of the expected results or outcomes of the study.
3. Purpose of hypotheses: Is similar to that of research objectives and questions.
A hypothesis specifies the variables you will measure
Identifies the population you will examine
Indicates the type of research
Directs the conduct of your study
Hypotheses direct the conduct of a study by influencing the study design, sampling
technique, data collection and analysis methods, and relationships identified in
previous research, proposed by theorists or observed in practice.
4. Types of hypotheses (four categories): Causal verses associative- type of
relationship presented in the hypothesis
Simple verses complex.- number of variables in the hypothesis
Directional verses non directional- Relationship direction or lack of direction in the
hypothesis
Null hypothesis verses research - Relationship expressed in the research hypothesis
- no relationship expressed in a null hypothesis.
5. causal hypothesis: Proposes cause and effect relationship between variables in
which one causes the other.
The cause is the independent variable
The result or outcome is the dependent variable
6. independent variable: Manipulated or varied by the researcher to have an effect
on the dependent variable.
Intervention, treatment, or experimental variable
7. dependent variable: Measured to examine the effect created by the independent
variable.
Outcome or response variable
8. research question: a concise, interrogative statement written in the present
tense that includes one or more variables
9. associative hypothesis: Proposes relationships among variables that occur or
exist together in the real world, so that when one variable changes, the other
changes.
10. simple hypothesis: predicts the relationship between only two variables.
11. Nondirectional hypothesis: research hypothesis that does not predict a partic-
ular direction of difference between the population like the sample studied and the
population in general.
