If you've been collecting speed data, you'll have noticed already that we don't all move at the same speed. What's causing the difference?
Does it have to do with how long you've been a citizen? Maybe you move faster if you've been around longer? If that's the case, by plotting each citizen's Whyville lifetime on the x-axis and speed on the y-axis, you would expect to see a pattern emerge, perhaps a line that slants up. If the graph is a complete mess, with no pattern to speak of, then there is probably no relationship between lifetime and speed. Remember though that even when you see a pattern, it only shows that there is a correlation. This might be the cause, but it's not for sure.
Use the drop-down menu to choose what data to plot the speed data against. Take a look at all the different possible causes we've suggested. Which one is correlated with speed? Post your thoughts in the BBS below.
