# The Big Mac Economy

Hard
Ever wondered why the Big Mac costs different amounts in different countries? Let's find out by comparing the GDP per capita of various countries to the price of the Big Mac in each country. We'll use a computer to analyze the data and create charts to help us understand the results.

## Hypothesis

The hypothesis is that as the GDP per capita of the country increases, the price of the Big Mac also increases.

## Method & Materials

You will select 10 countries based on their GDP per capita, research the GDP per capita and the price of the Big Mac in each country, create two charts to compare the data, and analyze the results.
You will need the GDP per capita of various countries, the price of the Big Mac in various countries, and a computer to help analyze the data.

## Results

The results show that in countries with a GDP per capita income that is less than US\$25K, typically the price of the Big Mac is greater than the GDP per capita income, per US\$10K. For the countries with a higher GDP per capita, the price of the Big Mac is less than the GDP per capita income, per US\$10K. The only exception is Switzerland. Increasing the GDP per capita income does not have much influence on the Big Mac selling price in the particular country.

## Why do this project?

This science project is interesting because it uses the Big Mac Index to compare the currency exchange rate between two countries and to determine whether the currency is undervalued or not.

## Also Consider

Experiment variations to consider include comparing prices of other international food chains like Pizza Hut or Burger King, and comparing prices for countries within Asia and countries within Europe.
