Monday...back to work! And a new unit!

New stuff today! Scatterplots, correlation, association...all that good stuff!

Tonight, please complete the following:

page 160: 1, 3, 5, 7, 9 (hint below)

*****For #9 you have to make a histogram of the distribution of "# of broken pieces." To do this, you should have "# of broken pieces" on your x axis; for a histogram, the y-axis is always frequency. So in this case, frequency is the same thing as "# of batches."

So, first, think about the lowest and highest numbers of broken pieces. In this case, we have discrete data (integers 1-6), so our bins will be centered over each # (1 - 6). Then, think to yourself....how many batches had 1 broken piece? This is your frequency...

PS...another reason that it's so dark when you're super-deep in the ocean is because everything down there is so ugly, so no one wants to see it. I think that's a scientific fact. Check these things out....
