Document Summary

Dividing the population into subgroups and then sampling from 1+ subgroups best describes : random sampling with replacement, random sampling without replacement, stratified random sampling, descriptive random sampling. Single-case experimental designs: experimental design with 1 participant (n=1, not a case study (case study=descriptive/observational; no variables are manipulated, single-case experimental designs involve manipulation of iv and dv. When you can assume generalizability: chemistry process of electrolysis in water can be observed in any body of water; results will be the same. Rare population: unusual disorders hm with no memory. Principles of single-case experimental designs: iv: operational definition: specific descriptions of procedures, materials/apparatus, procedure, active rather than passively manipulated; only 1 variable is changed at a time to document experimental control. Principles of single-case experimental designs: dv: must be operationally defined, measured repeatedly n=1; this is critical for comparing different conditions. Important because the critical comparison is between level of symptom scores reported or observed during phase.
