PROGRAMED INSTRUCTION
The purpose of this subcourse is to introduce you to basic descriptive statistical methods and
their applications. These methods can aid managers in the analysis of problems and in decision
making.
Concepts, principles, and methods for working problems and learning techniques of basic
statistics are presented in programed format. Graphs, drawings, and charts are included to give
emphasis to the applications of statistics.
The text contains frames (units of instruction) each of which presents a concept, principle, or
technique. You are asked questions or given problems to work to ensure that you understand
the material. Self-examination and appraisal are means by which you may measure your
progress and work toward self improvement.
Begin with Frame 1 and work through the programed text in a systematic, step-by-step manner.
You have the opportunity to check your work as you proceed from frame to frame. Though not
required, a hand calculator with a square root function would be helpful in working problems.
The answer to a question in a frame appears on the following page. In this way, you receive
instant feedback on whether you are correct or incorrect. If you answer incorrectly, return to the
frame and restudy the material for greater understanding.
The frames in this programed instruction text are numbered consecutively from Frame 1 through
Frame 72 as follows:
