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

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.

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.

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.

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.

Hey there! Here are some awesome videos about this science project that we think you'll really like. They're not only super fun, but they'll also help you learn more about the science behind the project. So sit back, relax, and get ready to have some fun!!
