The human resources (HR) manager for any LLC wants to give a short survey to a sample of recent hires (defined as people who have been with the company for less than one year). This sample will include several thousand individuals. The HR manager wants to be able to develop a confidence interval for the proportion of new hires that are happy with the company.

To get the sample, he has two plans:

Plan 1: Stand at the door as people are entering and leaving a quarterly employee communications meeting. Whenever he sees someone with a red badge, which indicates less than one year with the company, he will stop that person and give him or her a packet with the survey and instructions.

Plan 2: E-mail new employees with the packet attached and request they complete it and e-mail it back within three days.

Which planned approach would you use and why? Base your decision on statistical fact, potential cost, and HR management time to evaluate the results. You can assume that a reasonable estimate for the proportion of new hires that are happy with the company is .8.

Solution

Plan 2 approach wouls be effective in this survey case. The response rate will certainly be higher (with respect to average response rate in online surveys) due to the probabilistic sampling and the higher hapiness estimate of the census. This survey strategy will have less bias or sampling error. Data collection & management will be easier .

The recent hires would participate eagerly in companies procedures and the survey would result to be effective. In this case, the HR management time spent will be less and will lead to certain delivery of the message(survey). Hence, the postential cost will be very low compared to alternate plan 1.

Plan 1 would not be effective because that mostly employees preferred online survey approaches to the traditional format. There is contact basis (not anonymous) of deliverance which might influence the surveydata. It is time taking and could cause ineffective delivery of packets.
