In order to learn about the political attitudes of all students enrolled at Western Washington University, Professor Martinez randomly selected 900 of these students to complete a questionnaire. In this instance, all the students enrolled at Western Washington University are considered to be this.

A test that fails to measure what it is designed to measure lacks this.

What is validity?

500

A researcher who strongly believes that genetic influence is the major factor in human intelligence is analyzing data about identical twins that have been separated at birth and reunited in adulthood. The researcher observes many similarities in personality and habits within the twin pairs but does not notice differences within the twin pairs that might argue against the student’s belief. This student’s behavior illustrates this issue in research.
