Like many online surveys, this one raises more questions than it answers. Who and how many are the readers of "CFA Institute NewsBrief"? Are they CFA charterholders? Although clearly not a random sample, is 820 a statistically significant number of responses? How were the 5 possible responses selected? Why was an "other" response not provided? A reader of CBOK may have included "Productivity Trends", "Technology Trends" or "Public and Private Debt Levels". Each response is open to a wide degree of interpretation, so it is not clear what specific factors respondents are referring to. My observation is that the phrasing of the response with the highest degree of emotive content received the highest percentage response. Is this the intervening variable?
