What are the two main methods of primary data collection processes
Simple, Primary and Secondary Data
Laboratory-based data collection involves collecting data in an environment where all the conditions and variables are controlled, so that you are only measuring the variables in question.
Primary sources of data are original and collected directly by the researcher, like surveys, interviews, and experiments. They provide first-hand, unprocessed information. In contrast, secondary sources are based on existing data that has already been collected and analyzed by others, like books, articles, and reports. Primary data is more accurate and specific to the researcher's needs, while secondary data offers insights from already available information.
