1995 Annual Employee Survey" conducted by Office of Personnel Management that examines the working environments of federal employees. During the years 1994 through 1995, respondents were either promoted or not promoted (coding as 1 for promotion and 0 for no promotion). We would like to determine the promotion rate of survey respondents. To do so, we examine the frequency of promotion and no promotion.
Determine the following:
What is the absolute frequency of people who were promoted?
What is the absolute frequency of people who were not promoted? 13.17%
What is the absolute frequency of people who did not complete the survey? _8.9%___
What is the absolute frequency of people who completed the survey? _91.1%___
5. Calculate therelative frequencies (percent and valid percent) in order to complete the frequency table.
6. Calculate the cumulative frequencies.
