that attribute and uninfluenced by any extraneous factors

ErrorAnswer - extraneous influences that will cause the raw score to deviate from the
true score; (random error + bias)/systematic error

Random ErrorAnswer - variation from the measure's true score due to unsystematic
or chance factors, present if you get different results when the same measure was
used multiple times

Systematic ErrorAnswer - aka bias, error that consistently pushes scores in a given
direction, worse than random error bc leads to inaccurate conclusions

Strategies for Minimizing ErrorAnswer - standardization of experiments, reduce
scorer biases

subpopulations or categories

Cluster Random SamplingAnswer - dividing the total population into groups and
randomly selecting which groups participate

Non Probability SamplingAnswer - everyone in a population of interest does NOT get
an equal chance of being recruited, creates bias

Convenience SamplingAnswer - nonrandom selection of participants readily
available to the researcher

Quota SamplingAnswer - freely choosing any participant as long as they meet an
established quota

Purposive SamplingAnswer - sample chosen based on who the researcher thinks
would be appropriate for the study

Snowball SamplingAnswer - existing study participants recruit future participants
