no bias in sample selection
Stratified sample
a selective reproduction of the population
non-probability sampling
a sampling technique in which there is no way to calculate the likelihood that a
specific element of the population being studied will be chosen
Reliability
the concept that results can be repeated and are not just a fluke
Validity
The results indicate what the researcher thinks they indicate
Internal validity
includes research design and steps of the scientific method
