PURPOSE:
I want to find out if most people will be fooled by the arrow illusion. I wanted to do this because my brother found an illusion program on the Web. The program was called Dreamweaver.
HYPOTHESIS:
I think at least 70% of the people will be fooled by the optical illusion. I think that fewer older people will fooled by the illusion. Young people are those in 6th grade or younger.
PLANNED
PROCEDURE:
I plan to make a picture of the illusion, a record sheet, and a circle graph of the results. I plan to ask 60 people which line segment is longer. I plan to publish my results on the Web.
RESULTS:
I found out that 44.3 % got the first figure wrong. The best group on the first figure was the Old people. They were fooled only 35 % of the time. The worst group was the Young people at 51.4 %. On the second figure, 80.3 % were fooled. The best group on figure two was the old guys again. And the worst was the girls (ha, ha). On the last figure,
the best groups was the males. The worst group was the females, again.
CONCLUSION:
I was very close on my hypothesis. On figure one, I was too high because the arrows were all going the same way. On figure two, I was right. The percentage was 80.3 for all groups. The percentages ranged from 70 % for the old guys to 89.7 % for females. On figure three I was right. The percentage for all groups was 77.7 %. The range was from 73.1 % for the males to 82.8 % for the females.
