Ashford University BUS 308 statistics for managers Week 2 DQ 2 Variation

Variation. Variation exists in
virtually all parts of our lives. We often see variation in results in what we
spend (utility costs each month, food costs, business supplies, etc.). Consider
the measures and data you use (in either your personal or job activities). When
are differences (between one time period and another, between different
production lines, etc.) between average or actual results important? How can
you or your department decide whether or not the variation is important? How
could using a mean difference test help?
