Answer:
False
Step-by-step explanation:
A visual diagram of research hypotheses is not a mandatory requirement in quantitative reports. While visual diagrams, such as flowcharts or conceptual models, can be useful for illustrating the relationships between variables or outlining the theoretical framework of a study, their inclusion is not a strict requirement. The content and structure of a quantitative report may vary depending on the specific requirements of the research field, journal guidelines, or individual preferences of the researcher or author. However, including visual diagrams can often enhance the clarity and understanding of the research hypotheses and overall study design.
