There are two main types of research: quantitative and qualitative. Quantitative research uses numerical data and statistics to understand things like popularity, while qualitative research explores people's opinions and perspectives through open-ended questions. Primary research involves collecting your own original data through methods like interviews or surveys, while secondary research analyzes existing data from other sources. Demographic and psychographic research categorize people by attributes like age, gender, beliefs and lifestyle to identify appropriate target audiences. Proper research is essential for media projects to develop high quality products that appeal to target markets and ensure financial viability.
