What will I learn?

The Counting Principles Course provides practical tools to design efficient subscription surveys, from defining attributes and levels to computing total profile spaces using permutations and combinations. Learn to select pilot sets from large designs, check feasibility and divisibility for balanced assignments, and use counts to manage respondent burden, optimise sample size, and justify design choices with clear, data-driven reasoning.
