Welcome to Statistics

Computer Project - World Correlation:

• Get some data: Find any two things of interest from the website listed below
• It will work best if they are the same units (so both % or relative values) IE % of woman working and fertility rate would work. As opposed to Population of a country and % woman working, probably not.
• Start at this database
• Find at least 20 countries, choose some rich ones, some poor ones. Pick two variables that you think are correlated (have a relationship) - check with me before you get too far.
• Enter the country name and each variable on your spreadsheet (like this - made up data)
• Create a scatterplot
• Add a linear trendline - is it appropr0iate to add a linear trendline? - find the equation of the trendline. (VIDEO HOW TO)
• Find the correlation coefficient (r) [square root of r2]
• What countries are outliers? Discuss reasons they might be outliers.
• Describe the relationship and a conclusion (just 2 sentences describing the relationship and any insights)

Rubric:

Exceeds: conclusion is thorough. Outliers are well identified. Data is same units (as described above). Graphically layout nicely.

8 point project

• 1 - 2 variables chosen that are interesting
• 1 - scatterplot is created
• labeled (.5 points)
