6. Where Do We See Statistics? Statistics is used in almost ALL fields of human endeavor. – Sports: a statistician may keep records of the number of yards a running back gains during the football game OR number of hits a baseball player gets in a season – Public Health: an administrator might be concerned with the number of residents who contract a new strain of flu virus – Education: a researcher might want to know if new teaching methods are better than old ones.
