foundation of the result of elements c and d, does the heart of the distribution for overall plant conceal percent seem to be various on the areas? the opposite measurements within the info set. locate this size. (In part 2.8, we name this worth an outlier). c. Delete the outlier of half b from the knowledge set and recalculate the measures of crucial tendency.
