I teach university-level sociology and statistics, and use this blog to post data notes about social inequalities and social movements (and sometimes photos of renovations I do on my Victorian house in downtown Indianapolis)

Pi-Hat
In preparation for the statistics class I'm teaching for the spring, I could not find a way to create a "pi-hat" using Word or unicode, which is the symbol for a sample proportion. I need it in my "confidence intervals" lecture. I could use unicode to create "p-hat" and "pi" but not "pi-hat." I even Googled images, but could not find any existing images of pi-hat, except for degraded quality scans of textbooks. So I created an image of the symbol using Paint Shop Pro. So if anybody else needs an image of pi-hat, here you go!
