300
The section of a research paper that is a one-paragraph summary of the entire abstract
What is the abstract?
300
The degree to which we can say that we found an accurate relationship among variables in that changes in one variable are caused by changes in another variable
What is internal validity?
300
Definition of an observational measure
What is a measure that is rated by observers and sometimes made without the awareness of the person performing the behavior.
300
Two types of criterion validity
What are predictive and concurrent validity?
300
A measure that is made of behaviors or situations without disturbing the naturally occurring behavior or situation in order to reduce changes that might occur if there was awareness of measurement.
What is an unobtrusive measure?
400
3 components of an experiment
What is a variable you manipulate (the IV), a variable you measure (the DV), and random assignment?
400
The degree to which we can say that the results of study are accurate for different types of people in different settings assessed with different procedures.
What is external validity?
400
Age, height, and weight are examples of things you would measure for this scale of measurement.
What is an example of a ratio scale of measurement?
400
4 kinds of construct validity
What is content, convergent, divergent, and criterion validity
400
The measure of central tendency and the measure of variability you should use when your data is skewed
What is the mean and the observed minimum and maximum?
500
The definition of power in a study
What is the ability to find statistical significance when in fact a pattern or relationship exists? Sample size and the strength of the relationship between two or more variables are two factors that impact a study's power
500
A variable that is not the focus of the research study, but affects the variables of interest in the study
What is a confound (or confounding variable)
500
The score that is computed form items assessing a particular construct, most commonly a sum or average of the numbers representing responses to individual items in the document
What is scale score?
500
definition of test-retest reliability
What is a measure of the stability of scores on a scale over time?
