Experimental Design
- #Design randomized controlled trial for psychology study on memory intervention. Help me: 1) Define independent and dependent variables clearly, 2) Determine randomization approach (simple, block, stratified), 3) Calculate sample size for adequate power (0.80), 4) Control for confounds and extraneous variables, 5) Decide between-subjects vs within-subjects, 6) Plan blinding procedures (single vs double), 7) Consider demand characteristics and how to minimize

Sampling Strategy
- #Design sampling strategy for survey research on rural healthcare access. Help me: 1) Choose sampling type (probability: simple random, stratified, cluster vs non-probability: convenience, purposive, snowball), 2) Calculate required sample size with margin of error, 3) Address sampling frame and coverage issues, 4) Plan for non-response bias, 5) Design recruitment strategy, 6) Estimate costs and timeline, 7) Consider representativeness vs feasibility trade-offs
