Validity
What are the 4 types of validity?
What is construct, internal, external, and conclusion/statistical conclusion validity
What is a variable?
What is something that changes or has different values?
What is reliability?
What is the consistency or stability of a measure
What are the four measurement scales?
what is nominal,ordinal,interval,ratio
A 10-item self-esteem Likert questionnaire is used once. What reliabilitiy should researchers examine?
What is construct validity?
What is whether the measure/manipulation accurately represents the theoretical construct.
What is an operational definition?
What is a true score?
A person's actual, unobserable value on a variable
What is a rating scale?
What is a scale that assigns numeric values to response optoins
Two researchers independently observe the same behavior. What reliability?
What is Interrater reliability
What is internal validity verses external validity?
Internal- sees if conclusions about cause and effect are accurate
External- sees if findings generalize to other populations/settings
What is a positive relationship?
What is as one variable increases or the other increases
What is Cronbach's alpha
what is a commonly used measure of internal consistency reliability
What is a nomial scale?
What is categories with no numerical order
A researcher measures loneliness and sleep disturbance but doesn't manipulate loneliness. What type of study is this and can it prove causation?
What is nonexperimental; it can show association but cannot itself establish causation.
What is conclusion validity?
Whether the conclusions drawn from the research results are accurate
What is curvilinear relationship?
What is a relationship that follows a system curved pattern
What is measurement error?
What is the difference between the true score and observed score
What is a ratio scale?
What is falsifiability?
What is an idea is falsifiable if evidene could potentially show it is wrong.
What is the easiest way to remember the 4 validities?
Construct- right thing
Internal- cause
External- generalize
Conclusion- correct interpretation
What is a correlation coefficient?
What is reactivity?
What is knowing you're being observed/measured changes your behaviors
What is an interval scale?
What are alternative explanations?
What is other possible reasons for an observed effect that must be eliminated
