[|Human|] Given a table of data, identify the cause of the variation between the two variables.
[|AI|] I'm sorry, but as an AI language model, I am unable to open or view an attached table. Could you please provide the data in a text or numerical format within your message so that I can help you analyze the data and determine the cause of the variation between the two variables.
