Experimental designs

British Journal of Nursing, 1996
This article discusses randomized clinical trials, double blind designs and factorial designs and describes and explains their main requirements. It is shown that the randomized clinical trial is not a different experimental design, but is one that reflects the purpose for and the scale on which the post-test only or pretest/post-test designs are ...

Experimental design

WIREs Data Mining and Knowledge Discovery, 2012
AbstractMaximizing data information requires careful selection, termeddesign, of the points at which data are observed. Experimental design is reviewed here for broad classes of data collection and analysis problems, including: fractioning techniques based on orthogonal arrays, Latin hypercube designs and their variants for computer experimentation ...

To Design Experimental Research

The American Journal of Nursing, 1962
DURING THE PAST SEVERAL years, increasing emphasis has been placed on the need for nurses to examine nursing practice critically and scientifically. The conscientious and alert nurse is often concerned about the effect of a particular nursing practice, the relative effectiveness of different approaches, and numerous other questions which can be best ...

The basic experimental design

British Journal of Nursing, 1996
This article considers the three essential characteristics of the basic experiment (random assignment of subjects, manipulation of relevant variables and control of irrelevant variables) and describes the two most common experimental designs: the pre-test/post-test design and the post-test only design.

Factorial experimental designs

International Journal of Injury Control and Safety Promotion, 2016
Intervention studies are typically performed as ‘experiments,’ in the sense that a single ‘factor’ is allowed to vary while the others are held constant or accounted for in the analyses.

Quasi-Experimental Designs

Journal of the American Academy of Child & Adolescent Psychiatry, 2000
In earlier columns, we introduced 2 types of independent variables, active and attribute. The randomized experimental and quasi-experimental approaches both have an active or manipulated independent variable, which has 2 or more values, called levels. The dependent variable is the outcome measure or criterion of the study.

Randomized Experimental Designs

Journal of the American Academy of Child & Adolescent Psychiatry, 2000
In the last column, we discussed quasi-experimental designs and some of their weaknesses. Remember that quasi- and randomized experimental designs both have an active or manipulated independent variable, but in randomized designs the participants are randomly assigned to the experimental and control groups.
