Experimental Designs
This is when the researcher cannot randomly assign experiment participants to the groups but the researcher does manipulate the IV and measure a DV.
What is a quasi-experimental design?
The features of the experiment that inadvertently lead participants to respond in a particular manner.
What are demand characteristics?
This is how well an experiment is done and that there is no confounding variables
What is internal validity?
This is the number that appears the most in data.
What is the Mode?
This is the belief that explanations of phenomena and events should remain simple until the simple explanations are no longer valid.
What is the principle of parsimony?
This is the simplest possible factorial design.
What is a 2x2
A Latin phrase that means “after the fact”, this study examines the potential effects of variables that have already occurred.
What is ex post facto study?
You are able to imply conclusions to the general population
What is external validity?
This statistics test compares the means of two groups and determines the significance of the difference between them
What is a t-test?
A formal statement of the reaction among the variables or factors of interest in a particular research area
What is a theory?
An experimental design with two or more independent variables
What is a factorial design?
If you use the right kinds of experimental controls, you will avoid ____________
What are Confounding Variables?
This control procedure that achieves group equality by distributing extraneous variables equally to all groups.
What is balancing?
An experiment includes 90 participants: 30 of each are randomly assigned to one of the three treatment to one of the three treatment conditions. To analyze the group mean differences between these levels, a _____ is conducted.
What is a one-way ANOVA with independent samples?
An attempt to organize certain data and specific relations among variables within a specific portion of a larger theory.
What is a hypothesis?
This is the number of groups in a 3x4x3 factorial design
What is 36?
When overlooking data, the researcher should be ____________
What is inconspicuous?
This threat to internal validity involves the participants getting better test results due to taking the same test multiple times.
What is the testing effect?
This scale has a true zero.
What is ratio?
This is when someone seeks to answer research questions by observing behavior in the real world.
What is naturalistic observation?
This research design provides more control because they guarantee equality of the two groups?
What are correlated group designs.
Research findings that can be applied at any time, not only certain periods of time.
What is temporal generalization?
A threat to internal validity that can occur if experimental participants from different groups drop out of the experiment at different rates.
What is Mortality?
A probability value equal to 0.07 would be interpreted as this.
What is near statistical significance?
In naturalistic observation, it is in the best interest of the researcher to be as unobtrusive as possible, but this method allows them to become a part of the group being studied
What is participant observation?
