Data frames are objects that can load data from a spreadsheet and allow you to make calculations and charts from that data. Like the Math library, add the use block for a DataFrame library and create an object. Then run the program to see some of the data.

Hint
Great job!
Try again
Drag the use block for the DataFrame class, use Libraries.Compute.Statistics.DataFrame, and the DataFrame object, DataFrame frame. Remember, use blocks are always placed at the top of the program. This makes sure the program knows where to look for any library you might use later in your program. Once you have added the use and DataFrame object block, run the program and check your answer.
