Verified step by step guidance

1. Understand the difference between primary and secondary data: Primary data is data collected directly by the researcher for a specific purpose, while secondary data is pre-existing data collected by someone else for a different purpose.
2. Identify the key advantage of primary data: Primary data is tailored to the specific research question, making it more relevant and specific to the study's needs.
3. Evaluate the options provided: Consider whether primary data is always less expensive, more accurate, or easier to obtain compared to secondary data. These statements are not universally true.
4. Recognize that the correct advantage is that primary data is more specific and relevant to the research question, as it is collected with the study's objectives in mind.
5. Conclude that the main advantage of primary data in probability studies is its specificity and relevance to the research question, which makes it more suitable for addressing the study's goals.
