Comparing Estimates

By Megan Black

Introduction

In this project I' going to show you data that I have collected over the past few weeks. I have asked 28 people, what do you think the population of the UK is. The ages of people that I have asked are from 11-61. A wide variety of answers have come in, some are amazingly close, some are incredibly low and some are way too high.

My Data Table

Why I think People Guessed This

High: I think people have been to the UK and have seen many people there. It is really easy to guess to high when you go to cities in the UK because it's always busy. There are many people that have been to the UK and know people who live/lived there. They might come from small countries that have small populations and go, "The UK is bigger than Austria (just an example) so I think the way to think is that the answer has to be bigger than Austria's population."

Low: Some people who have guessed way too low might come from big places like Russia, America, Australia, India, China... and say, "If the UK is smaller than Russia (just an example) then the population is going to be smaller than the Russian population.

Just Right: Two people that were really close to the actual answer were both British. My mom and Sam Fendt a boy in sixth grade. I think they guessed that way because I know for a fact that my mom has lived in Northern Ireland, Scotland and England, and I know that Sam Fendt has lived in England. So if they have lived there they have seen how many people there COULD be in the UK.
