- Qualitative researchers collect data by going into the field where subjects conduct their normal activities, building trust without harming subjects, and participating minimally while learning subjects' perspectives. - Researchers must gain access and permission, establish rapport, be honest about their study and intentions, and not make promises they cannot keep. - Collecting data involves various techniques like observations, interviews, focus groups, and using tools like audio recorders with permission from subjects. Managing relationships, biases, and exiting the field responsibly are important considerations for qualitative researchers.
