How Many People in a Family?

Today you are going to learn to:

*define the way data will be collected
*make quick sketches of data
*describe the shape of data
*summarize what is typical of data

I called City Hall today and asked Mayor Clifton what the typical family size is in Nixa.  He told me the typical size family is about 3.  What do you think he means by that?

Do you think the typical size for our class might be the same as it is for our town?

Let's take a look at the data for our class.  If we're going to study family size for this class, how would we count who is in a family?

Today you are going to use snap cubes to build a tower to represent your family, one cube per family member.  Then we will arrange the towers in a sequence and then make a line plot of the data.  Will this data be quantitative or qualitative? 

What did you notice about our data?  What did you choose for a typical family size?  Why?

How would you compare our data to other classes in our school?  Are there some types of families that are not represented in our data?  How do we compare to the rest of Nixa?

Now we will work in our math stations.  Please listen to the directions of where you will be working today.
