9

What is used to establish the efficacy of treatments?

Explanatory Research

10

Explanatory research is capable of answering questions about?

Descriptive research involves what?

Descriptive Statistics

14

What considers the relationships that may exist between variables and involves correlation and regression?

15

What explores whether an intervention causes or affects one or more outcome variable and is the most demanding type of research that involves detailed methods?

Causal Research

16

Casual Research looks for what?

17

What type of research has a random assignment to groups and is capable of determining cause and effect relationships?

Experimental Research

18

What type of research has no random assignment and provides much less evidence about cause and effect relationships?

Quasi-Experimental Research

19

What type of research does not involve random assignment or even a comparison group and merely involves the observation of one group before and after an intervention?

Non-Experimental Research

When subjects are separated into homogeneous subgroups based on factors such as age or disease severity this is known as?

Blocking

26

Blocking enhances comparison because the subgroups are more alike than?

The intact groups

27

What is it called when the intact groups are separated into subgroups based on prognostic factors?

Stratified Randomization

28

What is assignment that is often concealed from researches to avoid the temptation of allotting patients with certain traits to groups that will receive special treatment?
