-data collected in naturalistic; real-world settings - Answers qualitative research (general definition)
concerned with providing accurate description of a phenomenon (either quantitative or qualitative) -
Answers descriptive research
goal is to identify relationships among phenomena (either quantitative or qualitative) - Answers
explanatory research
goal is to predict relationships among variables or differences between groups (quantitative) - Answers
predictive research
research to gain knowledge for the sake of knowledge (may be useful later) - Answers basic research
research to obtain knowledge to solve a clinical problem - Answers applied research
, -formal statement of the expected relationship between 2+ variables in a population
-tentative prediction
-includes: variables, population, proposed outcomes
-only used in quantitative research - Answers research hypothesis
states that a relationship exists between two behaviors. knowing the amount or kind of one behavior
helps you to predict the amount or kind of the other behavior - Answers Associative hypothesis
states that differences in the amount or kind of one behavior causes differences in amount or kind of the
other behavior - Answers causal hypothesis
1 independent variable and 1 dependent variable - Answers simple hypothesis
anything more than 1 independent variable and 1 dependent variable - Answers complex hypothesis
Predicts the existence of a relationship, not its direction - Answers nondirectional hypothesis
prediction regarding a positive or negative change, relationship, or difference between two variables of
a population - Answers directional hypothesis
(in a statistical test) states that there is no significant difference between specified populations, any
observed difference being due to sampling or experimental error
**you want your null hypothesis to be proven false, this helps support your actual hypothesis - Answers
null hypothesis
States that a relationship or direction exists between variables. Is scientific, substantive, theoretical, &
declarative. - Answers research hypothesis
-phenomena that can be directly measured
-qualities, properties, characteristics measured indirectly (like in a survey) - Answers variable
variable that influences that dependent variable; the intervention that is manipulated; the X variable -
Answers independent variable (IV)
outcome or variable that is influenced by the independent variable; Y variable - Answers dependent
variable (DV)
factors that interfere w/ the relationship between the IV and DV; if known ahead of time, may
sometimes be controlled statistically - Answers extraneous (confounding) variable
variable identifying the characteristics of the sample; e.g. gender, age, employment status - Answers
demographic variable
