  9. Planning Brainstorming Interpreting statistical results found in related studies Revising Research Questions to best utilize statistical methods Determining the type of data that you will need to gather or collect Determining how you will gather or collect that data Existing Data (e.g., chart review) Survey Pre/Post Assessment Experiment

  10. (Statistical) Study Design • Determining what variables need to be measured/recorded • Determining appropriate data collection instruments • Survey design • Experimental design • Determining sample size requirements (power analysis) • Establishing a timeline of data collection • Assist in developing and writing an evaluation plan
