Finding “the best” can be tricky when we can value different aspects in different ways. What is best for you might not be best for me. A way to include multiple aspects when ranking a number of “contestants” is to include weights.

Get data on the number of medals per country in the Olympics 2020. You can find that data in the file Medals.xlsx here: https://www.kaggle.com/arjunprasadsarkhel/2021-olympics-in-tokyo/version/7?select=Medals.xlsx

In the data file, the countries have been ranked in two ways, see columns Rank and Rank by total.

How would you rank the countries?

If you go by the total number of medals, what does that imply on the status and distinction between a gold medal and a bronze medal?

If you do not rank by the total number of medals, you need to add weights to gold, silver and bronze.
Which weights do you put on them? How would you decide?

What if you were to use the information from this article? https://www.bbc.co.uk/newsround/58028695

Should some other aspect be considered, for example, population, GDP, or altitude of the country? What would be “fair”?
