NAME: LiteracySleep.txt YEAR RECEIVED: 2003 SIZE: 93 variables, 429 observations COURTESY OF: V. Faye Jones, M.D. Department of Pediatrics University of Louisville REC'D ANALYSIS: Data mining NOTES: Data are from questionnaire survey attempting to determine the relationship between sleep hygeine and literacy. Literacy divided into four parts: language, environment, parental involvement, and reading, each of which is assessed separately in the questionnaire. Excellent data set for practice with data management and clean-up by sheer volume alone. Good set for data mining and investigation, particularly in data reduction, variable combination, and how to deal with missing data. DATA NOTES: Data are tab delimited. Text data are non-qualified, i.e. not delimited in any way.
