Today we're going to start our two-part unit on data visualization. Up to this point we've discussed raw data - which are just numbers - but usually it's much more useful to represent this information with charts and graphs. There are two types of data we encounter, categorical and quantitative data, and they likewise require different types of visualizations. Today we'll focus on bar charts, pie charts, pictographs, and histograms and show you what they can and cannot tell us about their underlying data as well as some of the ways they can be misused to misinform.

ChatterPix can make ANYTHING talk.
"ChatterPix is an app that converts pictures of inanimate objects into pictures that talk! All you do is snap a picture, draw a line to make it talk, and record your voice! ChatterPix can be used to make silly greetings, playful messages, and creative cards. In the classroom, ChatterPix can be used as a way for students to take pictures of their work and record information about it! A student's ChatterPix can be emailed, sent to YouTube, or saved on a device. Teachers can have student's save their ChatterPix creations in the camera roll on an iPad to review later."

Today we're going to talk about Chi-Square Tests - which allow us to measure differences in strictly categorical data like hair color, dog breed, or academic degree. We'll cover the three main Chi-Square tests: goodness of fit test, test of independence, and test of homogeneity. And explain how we can use each of these tests to make comparisons.

An interactive applet and associated web page that demonstrate a chord of a circle. The applet shows a circle and two draggable points on its periphery, with the chord drawn between them. A command button turns on the perpendicular bisector of the chord. As you drag the chord about, you can see that the perpendicular bisector always passes through the center of the circle. Applet can be enlarged to full screen size for use with a classroom projector. This resource is a component of the Math Open Reference Interactive Geometry textbook project at http://www.mathopenref.com.
