When formulating a hypothesis, the research question and purpose of the study determine the relationship between the variables. The hypothesis should propose how the variables are expected to relate or interact with each other based on the research question and study objectives. The hypothesis should be formed with consideration of the previous knowledge and evidence available in the field. Additionally, the lab materials and techniques used in the study may also influence the formulation of the hypothesis as they can provide insights into the possible relationships between variables. The thesis, on the other hand, is a more comprehensive framework that includes the hypothesis, research question, and purpose, but also incorporates a broader discussion of the research topic and potential implications.
