Final answer:
Research design, funding availability, the researcher's personal preferences, and participant availability all influence subject acquisition in research. All options are applicable.
Step-by-step explanation:
Factors such as research design, funding availability, the personal preferences of the researcher, and the availability of participants all affect how subjects are acquired for research.
When preparing for a study, a researcher needs to consider their personal, social, and physical readiness and sacrifices, as well as managerial aspects like how to handle personal effects and what organizational equipment and systems are necessary for data collection.
Before undertaking a study, planning the research design is critical as it provides a framework for analyzing both predicted and unpredicted data.
Selecting the right subjects is crucial as they differ in the quantity and quality of knowledge they can provide.
After the selection, a plan for asking questions and recording responses is developed, taking care to inform subjects of the study's nature and purpose, ensuring informed consent, and offering debriefing after the study is complete.
Choosing a random sample is an effective way to select participants because it ensures that everyone has the same chance of being part of the study, thereby increasing the study's validity and reducing selection bias.
