Can you predict a country's Winter Olympic performance?

It seems that certain countries are perennial powerhouses in the Winter Games. So, is there a way to use existing data to predict how many medals an individual nation will end up taking home? Two researchers think they may have found a solution.

In this lesson, students use scatterplots and linear regression to examine several variables that may help predict Olympic performance. Are the Winter Games largely decided before the opening ceremonies even start?

- Use a scatterplot to describe the qualitative relationship between two variables
- Interpret the results of a linear regression (equation and correlation coefficient) in context
- Make predictions about Olympic performance based on regression results
- Create scatterplots and best-fit lines from tabular data using technology
- Compare regression results for various explanatory variables
- Describe the strengths and weaknesses of using simple linear regressions, and examine the predictions of a multiple regression
