All 291 chapter members were invited to participate in our survey. From that invitation, we gathered 79 responses — a 27% response rate. We then analyzed the survey data using JMP software to sort, sum, and average data, and to create charts.
We wanted to determine the salary range of our chapter's membership, as well as the ranges or ages, breakdown of genders, and levels of education. We asked:
- Is there a difference in salary between people with different education levels?
- Is there a difference in salary between people with different amounts of experience?
- Do males earn more than females?
- Do those who have direct reports make more than those who don't?
In the graph below, the red line represents the mean of the salaries of those who took the survey, which was $61,761.02.
