The other day I posted about Julie's idea of collecting data to analyze by throwing paper airplanes. It took an entire hour to have 6 kids throw their planes five times, but we got some data to analyze.
Here was our agenda for today's class. They also had this on a handout for them to write on.
That was a good day when I had 6 class in this small mixed math class. Today, I had 3 kids (it met first period of the day). I made a table of each student's throw data. They found each of their averages. I asked what they noticed. We didn't have anyone throw in the 7 meter range.
Then, I asked them to put all 30 data points in an ordered list. That was a lot to ask, but we did it. We found the mean, median, mode, and range and I asked what they noticed about each. Interestingly, our mean was 7.52 meters even though we didn't have anyone who threw in the 7s.
We created a frequency chart together with me drawing it at the board and the kids doing it at their desks. We talked about why I chose these intervals.
Next, we made a histogram, stem and leaf plot, and a box-and-whisker. Three kids and three graphs, how convenient. We drew these together on their own sheet and once we knew they were correct, I had them to draw them on the board. Then, we did some more noticing.
Here is their work:
