Wide Format

Wide format is a common way of organizing Intensive Longitudinal Design (IL), or Experience Sampling Method (ESM) data.  The organization allows for multilevel modeling in statistical programs such as R. Each session is organized in a row, with prompts and other information organized by column. (Long format lists each prompt in a row.)
