Developing an Experiment

This guide outlines essential steps for developing a robust experiment. Begin by selecting relevant variables and specifying treatment levels. Control environmental factors and choose an appropriate experimental design. Properly assign subjects to groups based on demographics, and conduct a pilot test to refine your approach. Analyze collected data using statistical methods, ensuring survey questions are well-worded and Likert scales are employed effectively. Evaluate any unforeseen factors and ensure your case studies or interviews accurately represent the population.
