Nov. 5 - Creating Histograms

Assignment: Creating Histograms

Due: November 6, but no later than November 20 (last day of the trimester)

This assignment should take about 15 - 20 minutes? (this is a new assignment, so I am not sure)

Today we talked about histograms and how they differ from bar graphs (barely significant, but significant!) We are practicing reading them and now making one from a set of data. 

For the first problem, the frame is set up and just needs to be filled in. 

For #2, the students will need to determine the best ways to number the axes and create the bins, the labels, and the title. The tricky parts will be determining your what size of bins to use and then drawing them lines in equal intervals. The need to be meticulous and draw this well! If a graph is sloppy, it doesn't have the same impact.

These are the steps they recieved to follow:
Steps:

• Organize Data: Put the raw numerical data in order from least to greatest.
• Choose Bin Intervals: Divide the data range into equal-sized intervals (bins).
• Make a Frequency Table: Count how many data points fall into each interval.
• Draw the Graph: Label the x axis with the intervals and the y axis with the frequency.   
• Make sure the bars touch each other with no gaps

So how can you help?

Assist as much as you'd like. While you should not select the intervals for them, you can help them to map out the possibilities and see what makes sense. The cool thing about this assignment is that there is no right answer, but there are wrong ones. If the graph works and is fully labeled and accurate, we're good to go!
