in the context of design, researchers formulate hypotheses

Random sampling

increases external validity

A dependent variable is one that:

is measured

Empiricism

is the approach of collecting data and using it to develop, support, and/or challenge a theory.

Purposive sampling

is used when you want to study certain kinds of people, so you only recruit those types of participants

face validity

it looks like what you want to measure

leads researchers to pose particular questions

sampling only those who invite themselves
