Employees were asked to do an anonymous workplace satisfaction survey in January 2022. A new HR campaign to increase employee satisfaction was then implemented. In July 2022, employees were anonymously surveyed again (no pairing of the data took place). The HR department wants to know if there is there a difference in employee satisfaction scores from January 2022 compared to July 2022?
