Hi,
If you want to know more about the data set, type "?clouds" in the console and it will show the help page. You can take a look at the source paper if you want more information. It's also here:https://rdrr.io/cran/HSAUR3/man/clouds.html
If you want to see the data in a spreadsheet, find "clouds" in the "environment", which should be in the top right panel of your R studio.
Click on it and it will open the table on the left side.
You can also use "str(clouds)" command in the console to see the type of each column (variable).
It shows that sne is a "num" (numeric) variable. "rainfall" is also a "num", supposedly the amount of rain.
To make a statistical interpretation, you don't really need to know what SNE means and how it was measured.
From the graph, you just need to understand when SNE goes up by X amount, how much rainfall increases or decreases, in the cases of seeding and no-seeding.
Check the "simple linear regression" part in the lecture slides.
If you still have questions, feel free to ask us TAs in lab session or ask Darlene during office hour.
Hope this helps!
