What is This Project About?
Are people good at estimating big numbers? If you don’t know check out my math project where I surveyed 25 people (6th grade or older) on a question of the population of Russia. I need to write how much percent they were off. Then I need to write a paragraph about why I think people are estimating too high or too low. Let’s Begin!
Why I chose this project.
I chose this project because I like taking surveys and really like graphing data and this project allows it.
How did I find the percent people were off?
If a person guesses too high you need to subtract the estimate by the answer and then divide the difference by the answer. Then you got a decimal, you need to multiply the decimal by 100 to get a percent. When a person guesses too low you need to subtract the answer by the estimate and then divide the difference by the estimate. Then you got a decimal, you need to multiply the decimal by 100 to get a percent. If a person guesses 5% off or below he's correct.
Here is my Data:
In my project 48% of the people guessed too low, 32% guessed too high and and 20% of the people were correct. 60% of the people that guessed the question correct were Russian. I think it is because I asked the population of Russia and probably Russians know it better. Most of the people guessed too low, I guess that's probably because people don't know Russia's actual size. I also found out that people who live between 30 and 40 years old never guessed over 45% too high or too low. From this data you can see that people that are between 30 and 40 years old were the most accurate guessers. However a teen guessed most accurately and the least accurately. Maybe if I would ask more people between 30 and 40 years old then they probably wouldn't all guess over 45% too high or too low.
