Price changes

Scatter plots are an effective way of illustrating the relationship between two variables. In this exercise, you will examine the relationship between the daily price changes of two ETF funds: the iShares Russell 1000 Growth (IWF) and iShares Russell 2000 (IWM). There is a possibility of a relationship between the two as they both track the same type of index.

The CSV and DataFrames packages have been imported for you and the DataFrames iwf and iwm have been loaded and are available.
