What are the two main methods of primary data collection processes
In statistics, data collection methods can be broadly categorized into primary and secondary methods. Primary data collection involves gathering new data directly from sources through techniques such as surveys, experiments, interviews, and observations. Secondary data collection, on the other hand, involves analyzing existing data that has been previously collected, such as databases, reports, and academic papers. Both methods aim to ensure data is accurate, reliable, and relevant to the research question at hand.
Preliminary analysis will determine from the start whether the concept is viable. Interim analysis allows for continual data collection to influence the termination of the project.
There are both advantages and disadvantages of data collection methods in statistics. The main advantages are the metrics and correlation one can draw from statistics. The disadvantages stem from sampling errors.
Data Collection is involved in all methods of testing hypotheses.

Data collection
Pilot data refers to preliminary data collected in a small-scale study before conducting a full-scale research project. It is used to test the feasibility of the research methods, data collection procedures, and to refine the research questions before committing to a larger study.
