* Extra Credit Assignment.  Worth 10 points added to your homework score.  You must be present in class on Wednesday, July 20, to get the points, and you must both participate in the discussion in class and turn in (on Wednesday) a short written paragraph describing your experience.  Here is the assignment:  Pick a topic, suggestions are below.  See what data you can find on the web concerning this topic.  Use Google, and start with the key words "data" and your topic.  Are the data you find free or do they cost money?  Can you download the data set or do you need a computer program (or hand copy) to pull them off the web?  If you can download the data, can you load it into StatCrunch or do the data require "munging" to be used by StatCrunch?  What are the cases, and what are variables?  (If there are many variables, what are some of the ones that are of interest to you?)  Spend at least 45 minutes on this assignment.  If you finish with your first topic in less than 45 minutes, try another topic.  Suggested topics (actually, whatever interests you): sports (of various kinds, there are lots of free good data on baseball), entertainment, movies (again good data), law, criminology, government, city planning, architecture, weather, climate, geology, seismology, medicine, epidemiology, health, fitness, biology, evolution, extinction, ecology, math, computer science, statistics, data science, anthropology, ethnic studies, gender studies, history, sociology, culture, tourism, archeology, art, literature, writing, journalism, census, linguistics, finance, economics, business, astronomy, physics, chemistry, library sciences, theology, anything else you can think of.

You must be present in class on Wednesday, July 20 to get the points, and you must both participate in the discussion in class and turn in (on Wednesday) a short written paragraph describing your experience. Here is the assignment: Pick a topic, suggestions are below. See what data you can find on the web concerning this topic. Use Google, and start with the key words "data" and your topic. Are the data you find free or do they cost money? Can you download the data set or do you need a computer program (or hand copy) to pull them off the web? If you can download the data, can you load it into StatCrunch or do the data require "munging" to be used by StatCrunch? What are the cases, and what are variables? (If there are many variables, what are some of the ones that are of interest to you?) Spend at least 45 minutes on this assignment. If you finish with your first topic in less than 45 minutes, try another topic. Suggested topics (actually, whatever interests you): sports (of various kinds, there are lots of free good data on baseball), entertainment, movies (again good data), law, criminology, government, city planning, architecture, weather, climate, geology, seismology, medicine, epidemiology, health, fitness, biology, evolution, extinction, ecology, math, computer science, statistics, data science, anthropology, ethnic studies, gender studies, history, sociology, culture, tourism, archeology, art, literature, writing, journalism, census, linguistics, finance, economics, business, astronomy, physics, chemistry, library sciences, theology, anything else you can think of.
