The document discusses different research methods and techniques used in screenwriting and film production. It defines primary research as new information collected directly from sources like surveys, interviews, or focus groups. Secondary research refers to existing information found from outside sources like published articles or reference books. Qualitative research provides in-depth opinions and views, while quantitative research uses numerical data to measure responses. Effective primary research is tailored to specific questions but time-consuming, whereas secondary research is easier but may not answer all questions. Good research, both primary and secondary, is important for screenwriting to inform ideas, identify audiences, and impact planning and production.
