Human resource managers face the business problem of assessing the impact of factors on full-time job growth. A human resource manager is interested in the impact of full-time voluntary turnover and total worldwide revenues on the number of full-time job openings at the beginning of a new year. Data are collected from a sample of 63 “best companies to work for.” The total number of full-time job openings as of February 2017, the full-time voluntary turnover in the past year (in %), and the total worldwide revenue (in $billions) are recorded and stored in BestCompanies.
