100
The numbers on the back of football jerseys represent.
What is nominal?
100
A method of sampling where every individual in the population has an equal chance of being selected.
What is Simple Random Sampling?
100
A developmental psychologist visits a preschool and records how often children share toys without interacting with them.
What is Observational?
100
Consistency of participants' scores on a measurement over time.
What is Test-Retest Reliability?
100
Variance that is unaccounted for by the study variables.
Error Variance
200
Movie ratings (e.g., 1 star, 2 stars, 3 stars) are measured on this scale, which reflects rank order but not equal intervals between values.
What is ordinal?
200
The type of sampling where researchers select every nth person in a population list.
What is Systematic Sampling?
200
A psychologist asks participants to complete a questionnaire about their daily stress levels
What is Self-Report?
200
Degree to which two independent raters agree.
What is interrater reliability?
200
Researchers erroneously generalize results to a population that differs from the one which the sample was drawn.
What is misgeneralization?
300
A standardized IQ test.
What is interval data?
300
This type of sampling divides a population into subgroups before randomly selecting participants.
What is Stratified Sampling?
300
Researchers studying stress levels use a device to measure participants' heart rate and cortisol levels in response to a stressful task.
What is Physiological?
300
A test item appears to measure what it is supposed to measure.
What is Face Validity?
300
What is Cluster Sampling?
400
A scientist measures temperature in Kelvin
What is ratio?
400
This broad category of sampling does not give all individuals an equal chance of being selected.
What is Nonprobability Sampling?
400
A researcher uses fMRI scans to examine brain activity while participants watch emotional videos.
What is Physiological?
400
Items are not assumed to measure a single underlying construct.
What are Formative Measures?
400
This type of nonprobability sampling is the most commonly used in behavioral science research.
What is Convenience Sampling?
500
A team of scientists measures the weight of newborns in grams. Later, they divide each baby’s weight by the heaviest baby’s weight to express weight as a percentage of the maximum recorded value.
What is ratio?
500
This issue occurs when a sample does not accurately reflect the population from which it was drawn.
What is Sampling Error?
500
Using different methods to measure on variable.
What is Converging Operations?
500
A measure should correlate with other measures that it is designed to correlate with
What is Convergent Validity?
500
Sample Size, Population Size, Variance - this term is a function of all three of these things.
What is Error of Estimate?
