If, on a questionnaire, a respondent is asked “what do you feel is the most important crime problem facing the police in your city today?”, they are being asked what type of question?
What is open-ended question

This type of validity refers to the extent to which measures indicate what they intend to measure
What is measurement validity
100
Example: The ASI’s measures of drug and alcohol problems were related more strongly to other measures of drug and alcohol problems than to measures of other life problems (i.e. legal and family) (McLellan et al., 1985) Is an example of what type of Validity?
What is Discriminant Validity Discriminant validity is achieved when scores on the measure to be validated are similar to scores on another measure of the same variable and to scores on variables that measure different but related concepts
100
__________ is achieved when a measure yields consistent scores or observations on different occasions
What is Reliability
100
A mental image that summarizes a set of similar observations, feelings, or ideas
What are concepts? Examples: Poverty Social Control Strain
200
Surveys are best suited for studies that have what as their units of analysis?
What is individuals
200
The question, “how many days per week do you smoke marijuana”, has ______ _______ if used to measure the variable, “marijuana use”
What is Face Validity
200
In Selecting the proper level of measurement, Researcher selects the highest level of measurement appropriate as part of operationalization process, based on:
What are Characteristics of the concept Characteristics of the information source
200
This method for testing reliability looks at Measure obtains same results at two different times
What is Test-retest
200
The process of specifying what is meant by a term
What is Conceptualization
300
_________ ended questions are useful because they are more easily processed
What is Closed
300
Social researchers strive for ________ validity when no clear criterion exists for validation purposes
What is Construct Validity Validity can be established by showing that a measure is related to a variety of other measures as specified in a theory or other research studies
300
More than one observer measure the same phenomenon is an __________
What is Interobserver
300
The 2 Prerequisite for measurement validity
What are Valid measures are also reliable Reliable measures are not necessarily valid
300
This level of measurement is Qualitative and without a mathematical interpretation while the alternative is Quantitative and progressively more precise mathematically
What is Nominal vs. Ordinal, Interval, and Ratio
400
This allows us to collect data about individuals or groups without their direct knowledge or participation
What are unobtrusive measures?
400
__________ validity is achieved when scores obtained on one measure can be accurately compared to those obtained with a more direct or already validated measure of the same phenomenon
What is Criterion Validity Example: A probation officer checks self-reports of drug use with urine tests.
400
This type of research Translates portions of an abstract theory into specific variables that can be used in testable hypotheses
What is Deductive research
400
This type of observer measures the same phenomenon on separate incidents
What is Intraobserver
400
What type of measure would be found in this Example: Number of drinks an individual has consumed in one sitting.
What is Ratio Measure Fixed measuring units with an absolute zero point Zero means that absolutely no amount of the variable Ratios can be formed between the numbers

Surveys tend to be high on reliability and generalizability, but can have a weak point in __________________.
What is validity
500
The Michigan Alcoholism Screening Test includes 24 questions which experts have agreed capture the full range of possibilities of direct consequences of substance abuse. Is an example of this type of Validity
What is Content Validity A measure has content validity if it covers the full range of the concept’s meaning
500
In This method for determining reliability researchers Compare slightly different versions of measures
What is Alternate-forms
500
In this type of method for assessing reliability A survey sample is randomly divided in two. These halves of the sample are then administered the two forms of the questions and the scores are compared
