Correlation of Length and Speed of Trips
Figure
10.4
shows the correlation plots of trip length (in km) and speed (in
km
/
h). For each speed value
s
, the plot reports the distribution of distance
traveled by all trips with average speed
s
. For each value of speed the box plot
reports median, 25th, 75th, and 99th percentiles. Notice that with this specific
