You could then better test whether the time it takes depends on when you leave. (ie. do a t-test to test whether the slope significantly different from 0). The way the data is plotted now would be better for testing whether your departure time is correlated with your arrival time (which it should be pretty obvious that it is). Another thing you could look at is whether the variance changes depending on when you leave (ie, bin the departure times into, say, 5 or 10 intervals, and plot std dev vs start time.), though it looks like you might not have enough data for the earlier bins.Avihttps://www.blogger.com/profile/13914646098588326559noreply@blogger.comtag:blogger.com,1999:blog-18103977.post-2690880959698657462011-04-04T14:27:55.750-04:002011-04-04T14:27:55.750-04:00Was this in the Grandma-moblie or new car?
