The median is by far the most representable metric here. It shows the 50th percentile, or the middle price when the price list is sorted in ascending order. It looks like white and black cars take the lead, with orange taking a strong third position. On the other hand, green and pu...
A mechanism provided by R programming through which elements of a vector can be arranged in a particular order, usually facilitated by but not just limited to the order() function that assists in sorting the elements either in ascending or descending order, as required, with the normal use of...
