This learning unit on easy statistics is one in the Choice Series, a self-learning development program for supervisors. Purpose stated for the approximately eight-hour-long unit is to enable the supervisor to use statistics to improve his/her decision-making ability, interpret statistics and form judgments on the interpretations other people make, assess statistically a work team's performance, and use quick and practical statistical tests at work. An introduction provides an overview of the unit and lists unit objectives. Parts A through D contain informative material, activities and answer keys, self-checks and answer keys, and a summary. Topics include describing data, some basic statistics, a basic statistical test, and relationships and trends. Part E contains performance checks--an end check to be completed alone and a tutor check and work-based project. Part F consists of a brief unit review, extensions (print sources of additional information, such as units or sections in books), and a list of references. (YLB)
