Who is more easily tricked by optical illusions?

Optical illusions change the viewer’s perception of a piece of art to make them perceive it in a different way than it is in reality. A branch of optical illusions is geometric illusions where artists use angles, lines, spirals and other geometric shapes to change the viewer’s perception of their artwork. Geometric illusions show how the brain is trying to find patterns and orderly representation out of 2-D drawings. Optical illusions can also use color, light, and patterns to create images that can be deceptive or misleading to our brains. The information gathered by the eye is processed by the brain, creating a perception that in reality, does not match the true image.

When collecting statistical data, the examiner can use different methods trying to obtain their data. They can issue out a census, which is similar to the United States Census Bureau’s census they issue every ten years, which is a conducted study that gets input from every single person in a population. This is not typically done because of the time and money spent conducting and retrieving data from each survey. The examiner can also issue out a sample survey which is where they obtain their data from a subsection of a population so that they can estimate the characteristics of a population as a whole. Two other methods include an experiment, where they have a controlled study with independent and dependent variables, and observational studies, where they cannot control the subjects being tested, where the researcher will try to understand the cause-and-effect relationships with what they are testing. Whenever collecting data, it is important to get a variety of ages, genders, and racial backgrounds to get a wide range of people and their different circumstances. The variety helps get a more accurate response and percentage when collecting numerical

The UCLA Statistics Online Computational Resources (SOCR) Optical Illusions Survey was sent to 2,000 random UCLA students, both undergraduate and graduate, and faculty. They were emailed an online survey and the goal of this survey was to observe the different susceptibility to optical illusions between gender and age differences. In this survey, they were encouraged to respond to the email and answer questions to the following optical illusions that were linked inside of the email. All of the responders did so voluntarily so they were not forced to participate. The optical illusions included those of motion, color, appearance, and shape to see the different possible sex-linked diseases such as colorblindness. They were given 30 seconds to view each image before they would respond to the questions that followed them. The first image (Image 1) was a test to see which gender was more susceptible to colorblindness. They were asked to state which numbers they saw in the circles to test the different types of colorblindness. Through the second illusion, otherwise known as the Pacman Illusion (Image 2), it would test the susceptibility to motion illusions between the ages and genders. The people who were participating were asked to stare at the dot for 30 seconds and the result should have been that a green dot would appear in
