- Homework 7 (Chapter 14) - Part A
O The American Association of Individual Investors (AAII) On-Line Discount Broker Survey polls members on their experiences with discount brokers. As part of
the survey, members were asked to rate the quality of the speed of execution with their broker as well as provide an overall satisfaction rating for electronic
trades. Possible responses (scores) were no opinion (0), unsatisfied (1), somewhat satisfied (2), satisfied (3), and very satisfied (4). For each broker summary
scores were computed by calculating a weighted average of the scores provided by each respondent. A portion of the survey results follow (AAII website,
February 7, 2012).
