2. Approximately 7,000 people heard about the mc square during the conference 1,200 people stopped by the mc square booth and took a handout 107 people completed a survey which allowed them to evaluate the mc square The 2006 NSTA Conference

3. The Survey Participants and attendees of the NSTA Conference were given the chance to try the mc square. After the trial, participants were given a survey which asked them questions about their experience. Responses were given on a scale of 1 (most negative) to 5 (most positive).

4. 1. Which program did you like the best? P1 – Concentration ProgramP2 – Relaxation Program P3 – Right/Left Brain ProgramP4 – Deep Sleep Program 2. Did you like the Sound of Nature Program? 3. Was the mc square comfortable and easy to use? 4. How did you like the design? 5. How did you feel during the trial? 6. How did you feel after the trial? 7. Would you like more information about the mc square? 8. Would like to buy an mc square on 30-day approval? The Questions

5. Survey analysis showed that the majority of participants (71%) favored the P2 relaxation program. 19% of participants preferred the concentration program, while only 4% and 6% chose the right/left brain and deep sleep programs, respectively. The low number of people who preferred P4 is a result of the fact that very few people wanted to try the deep sleep program midday. Analysis across gender showed that 10% more women than men preferred the relaxation program. Favorite Program “Which program did you like the best?”
