What is Experimental Design
This is a type of research method that involves manipulating one or more independent variables to measure their effect on one or more dependent variables
What is Experimental Design
Some subjects are administered one or more experimental stimulus, while other subjects are not given such a stimulus
What is treatment and control groups
This true experimental design involves one treatment group and one control group. It is ideally suited for testing the effects of a single independent variable that can be manipulated as a treatment.
What is two group design
This type of quasi experimental design uses a pretest with cut-off scoring which determines how the treatment and control group are determined
What is Regression Discontinuity Design
Random sampling, inclusion/exclusion criteria, use of a comparison group, subject matching across groups, manipulation of the independent variable, single, double or treble blinding procedures, the use of precise measuring tools and the application of standardised statistical tests in the final analysis of data are considered____________
What are controls
This is the setting in-which experimental design is conducted (hint: there are 2 types)
What is laboratory and field
The process of randomly drawing a sample from a population or a sampling frame. It ensures that each unit in the population has a positive chance of being selected into the sample
What is random selection
This true experimental design involves four or higher-group designs. Each independent variable in this design is called a factor, and each sub-division of a factor is called a level. This design enables the researcher to examine not only the individual effect of each treatment on the dependent variables (called main effects), but also their joint effect (called interaction effects).
What is factorial design
In this quasi experimental design pretest information is collected after the treatment has already begun, or not collected at all
Proxy pretest design
The possibility that the observed effects (dependent variables) are caused by extraneous or historical events rather than by the experimental treatment
What is history threat
This subcategory of experimental design requires treatment manipulation as-well as random assignment
What is a true experiment
The process of randomly assigning subjects to experimental or control groups
What is random assignment
This type of experimental design is a combination of more than one type of design merged together.
What is a hybrid design
This type of quasi experimental design involves four groups; two control groups and two experimental groups, and utilizes pre-test post-test data
What is separate pre-test and post-test sample design
A threat in pre-post designs where subjects’ posttest responses are conditioned by their pretest responses
What is testing threat
This subcategory of experimental design requires treatment manipulation, but does not require random assignment
What is quasi-experiment
This helps control the “cause” in cause-effect relationships
What is treatment manipulation
This true experimental design is the combination of the pretest-post-test design or post-test only, and the inclusion of block design.
What is randomized block design
This type of quasi experimental design uses the pre-test post-test style of measurement, but measures two or more variables, and incorporates data from only one single group of participants
What is non-equivalent dependent variable design
Each of us experiences a different reality. Without taking this into account violates their fundamental view of the individual
What is ontological assumptions
