In determining the best companies to work for, a number of
variables
are considered, including size, average annual pay, and turnover
rate, etc. Moreover, employee
surveys are conducted in order to assess aspects of the
organization's culture, such as trust and
openness to change. In an attempt to determine what affects
turnover rate, a sample of 33
companies was randomly selected and data collected on the average
annual bonus and turnover
rate (%) for 2015. In addition, a questionnaire was...
