Experimental Research QUIZ!

An environment in which the researcher attempts to objectively observe phenomena that are made to occur in a strictly controlled situation in which one or more variables are varied, and the others are kept constant.

• Field Experiment

• Random Assignment

• Experiment

• Action Research

A study is conducted in the controlled environment of a laboratory where the researcher precisely manipulates one or more variables and controls for the influence of all or nearly all extraneous variables.

• Experimental Control

• Laboratory Experiment

• Field Experiment

• Internet Experiment

One of the ways to manipulate an independent variable is by giving the various comparison groups different amounts of the independent variables.

• Amount Technique

• Type Technique

The most powerful technique for equating groups in experimental research and, thereby, increasing the study’s internal validity.

• Analysis of Covariance (ANCOVA)

• Experimental Control

• Matching

• Random Assignment

A control method equates comparison groups that differ on a pretest or some other extraneous variable. It is useful when the participants in the various comparison groups differ on a pretest variable that is related to the dependent variable.

• Building the Extraneous Variable Into the Research Design

• Analysis of Covariance (ANCOVA)

• Counterbalancing

• Holding the Extraneous Variable Constant

The outline, plan, or strategy that is used to answer a research question.

• Hypothesis

• Research Question

• Research Design

• Matching

The group that does not receive the experimental treatment condition.

• Control Group

• Experimental Treatment Group

• Single-Blind Procedure

• Double-Blind Procedure

This is a strong experimental research design that is a popular term for experimental designs with random assignment of participants to experiment treatment and control groups and, if possible, the use of double-blind procedures.

• Single-Blind Procedure

• Double-Blind Procedure

• Randomized Controlled Trial (RCT)

• Pretest-posttest control-group design

A design in which two or more independent variables, at least one of which is manipulated, are simultaneously studied to determine their independent and interactive effects on the dependent variable.

• Factoral Designs

• Cell

• Marginal Mean

• Main Effect

The following are the steps in conducting experimental research, EXCEPT?

• Choose a Type of Experimental Design

• Form Hypotheses to Test Cause-and-Effect Relationships

• Participants will gain from the intervention.

• Select an Experimental Treatment and Introduce It
