Outside our comfort zone #MTBoS30 - 3

Students have been working on group projects this week.  They are working with real data and trying to make sense of it.  Trying to use it to make predictions, to make decisions.

Sometimes real data just doesn't fit the models we have learned.

So they ask tentatively, "What do we do?"

I ask, "What do you think the data is telling you?  Is there some reason why the data is skewed that way?  What might have happened during that time period?"

Students look puzzled, but they agree that they could research that.  Then they ask, "But what regression equation should we use?"

I reply, "For this project, you'll have to make a decision about what type of line makes the most sense.  Just be able to explain how you made your decision."

We are working outside our comfort zone and it is OK.

The present their projects on Thursday/Friday.  I can't wait to see the final products!
