100
Refers to the degree to which an assessment or test subjectively appears to measure the variable or construct that it is supposed to measure. When an assessment or test appears to do what it claims to do.
Face validity
100
A(n) _____ is a statistic used to determine if there is statistically significant difference between two related sets of scores.
t-test for dependent means
100
the group or condition that gets the key treatment in an experiment
experimental group
100
a group in which participants believe they are receiving the treatment, but in reality they are not.
Placebo group
100
the temporal stability of a measure at multiple sessions.
Test-retest reliability
200
A correlation can range from _____ to _____.
–1.0; 1.0
200
______ is the continued exposure to experimental conditions in a within-subjects study that increases the likelihood of hypothesis-guessing.
Sensitization effect
200
Confirms that the independent variable was, in fact, successfully manipulated. 
Manipulation Check
200
Statistical tests that allow us to test comparison between groups that we predicted ahead of time. Added benefit of combining two conditions so you can compare to a third.
planned comparisons
200
a group that does not receive any form of the treatment and just completes the dependent variable.
Empty control group
300
A correlation with a value of 0 means:
the variables are unrelated.
300
If a researcher wants to complete an initial assessment on a group of participants this is referred to as:
a baseline measurement.
300
The degree to which a study parallels everyday situations in the real world.
mundane realism
300
A studies ability to find difference between the variables.
power
300
Refers to how well an experiment is done, especially whether it avoids confounding more than one possible independent variable acting at the same time
Internal validity
400
Colleen was asked about her political attitudes on a survey in her sociology class. She did not want to seem politically overzealous so she indicated moderate levels throughout the rating scale. This is referred to as:
an error of central tendency
400
A _____ is a statistic used to test a hypothesis from a within-subjects design with three or more conditions.
repeated-measures analysis of variance
400
People who have agreed to be in a study are assigned to the various conditions of the study on a random basis. Each participant has an equal probability of being assigned to any particular condition
random assignment
400
Conducted whenever a significant omnibus difference between three or more sample means has been revealed by an analysis of variance (ANOVA)
post hoc test
400
Important tool for determining the strength of a cause and effect relationship. This is the process of establishing that the cause did indeed happen before the effect.
Temporal precedence
500
Granetta was completing a survey developed by her social club at school. Granetta agreed with every statement regardless of the actual item. This is an example of:
an acquiescent response set.
500
Mrs. Klein is having her social studies students assessed at multiple points throughout the academic year, after each academic module has completed. However, she does not need a baseline measurement. Mrs. Klein is conducting a:
repeated-measures design
500
How many factors are in two group designs?
one factor, one IV
500
A third variable or a mediator variable, can adversely affect the relation between the independent variable and dependent variable
Confounding variable
500
refers to the degree to which two measures of constructs that theoretically should be related, are in fact related.
convergent validity
