Choosing the Right Graph

How do you know which type of graph to use? If you need a frequency plot, do you use a dot plot, a histogram, a box plot?? When is it okay to connect the dots--do we need a scatterplot or a line graph? So many decisions! More...

The materials provided here include a Flow Chart and a Graph Table that will show you how to decide what kind of graph is needed to illustrate the data or question you are exploring.  Also included is a file containing one-page examples of small data sets with sample questions.  

Time Series 101

This short PowerPoint slideshow is a good orientation to Time Series data. What is it? How is it different from correlation data? Plus it has links to two helpful websites.

2. A fun 4-minute video animation showing time series in action

Telling Data Stories with Correlation Graphs

Show your students these graphs and ask them to answer the following questions: 1. What question is the graph addressing? 2. What story does the graph tell? And for Teachers: 3. What challenges would your students have interpreting this graph? Feel free to substitute other graphs for this exercise!

Population Pyramids

This activity teaches how and why population pyramids are useful and how to construct them (a file containing special graph paper is also provided). Students practice analyzing age-gender distribution graphs. Leading questions offer ideas for discussion. More...

NOTE: also see this website for some very cool interactive population pyramids showing world-wide and country populations over time http://populationpyramid.net/.
