 What are the CHARACTERISTICS OF “IDEAL” EXPERIMENTS?
Definition
 •Controlling the Time Order of Variables •Manipulating the Independent Variable Establishing Relationships Between Variables •Controlling Rival Hypotheses •Using a Control Group •Randomly Assigning to Groups
Term
 How do you Control the Time Order of Variables?
Definition
 –Independent variable must precede the Dependent variable
Term
 How do you manipulate the indepenpendent variable?
Definition
 –Using an experimental or control group
Term
 To control the rival hypotheses you:
Definition
 –Holding Extraneous Variables Constant –Using Correlated Variation   –Using Analysis of Covariance
Term
 In characteristics of ideal experiments, Randomly Assigning to Groups includes;
Definition
 Matched pairs
Term
 THREATS TO INTERNAL VALIDITY ARE?
Definition
 History, testing, matureation, instrumental error, statistical regression, differential selection of research participants, mortality, reactive effects of research participants, interaction effects and relations between the experimental and control groups
Term
 What does history mean when referring to internal validity?
Definition
 Outside events not taken into account during the research design.
Term
 In dealing with threats to internal validity, what does maturation refer to?
Definition
 physical or psychological change in the populations
Term
 When dealing with internal validity, what does testing refer to?
Definition
 Pretests at the starting point of a research desgin
Term
 When dealing with internal validity what does intrumental error refer to?
Definition
 Flaws in the instruments used
Term
 When dealing with internal validity what does Statistical regression refer to?
Definition
 The group of scores that tend to be high or low
Term
 When dealing with internal validity, differential selection of research participants refers to..?
Definition
 How different the participats are from one another
Term
 When dealing with internal validity, mortality refers to?
Definition
 Participants that may drop out of the study.
Term
 When dealing with internal validity Reactive effects of research participants refers to:
Definition
 Participants reacting to the "novelty" of the study
Term
 When dealing with internal validity, interaction effects refers to?
Definition
 The interaction of two threats to internal validity
Term
 When dealing with internal validity, Relationships betweem experimental and control groups refers to?
Definition
 Diffusion of treatments Compensatory Equalization Compensatory rivalry
Term
 What is Diffusion of treatments?
Definition
 Participants from the control group talk to participants from the experimental group
Term
 What is Compensatory equalization?
Definition
 Conpensation by staff to the control group
Term
 What is compensatory rivalry?
Definition
 groups become motivated to compete with one another
Term
 What are the threats to external validity?
Definition
 Pretest- treatment interaction Selection-treatment interaciton Specificity of variables Reactive effects Multiple-treatment interference Research bias
Term
 With regards to threats of external validity, pretest-treatment interaction refers to?
Definition
 The nature of a pretest can alter the way a participant responds to the intervention
Term
 With regards to threats of external validity, selection-treatment interaction refers to?
Definition
 The research design can not provide for random selection
Term
 With regards to threats of external validity, the specificity of variables refers to?
Definition
 A research project conducted with a specific group may not apple to another similar group
Term
 With regards to threats of external validity, reactive effects refers to:
Definition
 The attitudes of individuals taking the pretest are affects
Term
 With regards to threats of external validity, Multiple-treatment interference refets to..
Definition
 Two or more interventions that are given in succession
Term
