Psychology / Unit 1 Psych 0049 short lesson, about 20 seconds
Population and Sample
Captions available
The idea
A population is every case a researcher wants to describe; a sample is the subset actually studied.
In practice
The population is all first-year undergraduates in the country; the sample is 200 of them at one university.
Where people slip
Conclusions travel no further than the sample supports. A campus sample describes a campus.
