Validity This!
When people become wiser about the research design the design suffers this validity threat.
Maturation
The statement that contradicts what "you think the relationship between two or more variables are" is called this.
Null Hypothesis
Z-Scores conform to this standardized geometric shape.
The Bell Curve
The variable that is between the perceived cause-effect relationship is this.
Intervening Variable
When the researcher attempts to extrapolate the results they got from a study to the population at-large.
Generalizability
When the measurement design lacks accuracy it suffers this validity threat.
Instrumentation
Individuals, Groups, States, Countries, etc... are these for research purposes.
Units of Analysis
Karl Pearson's statistic to measure how closely two variables associate.
Correlation Coefficient
The variable before the 'causal' variable in a cause-effect relationship is this.
Antecedent Variable
When a group of professionals agree that the manner in which they rate a behavior is similar.
Inter-rater Reliability
In longitudinal research people may opt out of the experiment and cause this validity threat.
Attrition
Phillip Zimbardo's research on criminal behavior at a prominent university had to be stopped because it caused psychological distress.
Stanford Prison Study
The percentage of the sample that falls within two standard deviations is this percentage.
95%
The four characteristics that must encompass a variable like 'money'.
Categories, Rank, Numbers, and a Real Zero
When people have a similar perception about how they see or define their reality.
Intersubjectivity
The manner of sampling selection that minimizes the validity threat of 'selection'.
Probability Sampling
Non-Probability Sampling method that mimics a Stratified Random Sample.
Quota Sample
X marks the spot. The most appropriate statistic for measuring nominal level variables?
Chi-Square
When the variables associate but go in opposite directions when the I.V. is introduced with the D.V. it is this type of association?
Negative Relationship
When an experiment is created the conditions should mimic what would actually occur in the 'real world' like Dr. Milgram's Authority Study.
Mundane Realism
When something occurs outside the research design that influences the D.V. this validity threat is of concern.
History
When variables have categories and rank but no numbers it is this Level of Measurement.
Ordinal
The highest point where a normally distributed group of numbers lies is this Measure of Central Tendency?
The Mean
The types of mistakes associated with validity.
Systematic Error
When conducting an experiment multiple times and getting similar results the research design has ___________.
Reliability
