Figure 3.2 Question Responses by Age Group

The question had two possible responses: Agree and Disagree. There are seven age groups of respondents with 43 to 113 respondents per group. The youngest age group (25 - 29) was the largest group surveyed with 113 responses. The highest positive response rate was 84.1% in the youngest age group. The share chart displays the share of respondents who agree or disagree with the question for each age group. As age increases, the portion of respondents who agree with the question decreases. Thus, the older respondents tend to be working on their careers less than the younger respondents.

Tip: Colors on the charts can be defined by using the Value Colors column property. See Value Colors in Using JMP.
