Document Summary
Draw a single vertical axis spanning the extent. Draw short horizontal lines (hinges) at the lower (q1) and upper (q3) quartiles; also draw a line at the median (q2). Then connect them with vertical lines to form a box. Compute 4 fences (right) upper outer fence = q3+3xiqr (ight) upper inner fence= q3+1. 5xiqr (left) lower inner fence = q1-1. 5xiqr (left) lower outer fence= q1-3x1qr. Find the largest point between the upper inner fence and the upper hinge and draw a line from the top hinge tot his height and draw the top whisker. Find the lowest data point between the bottom hinge and the lower inner fence and draw a line from the bottom hinge to this point and draw the lower whisker. Mark data points that occur between each pair of upper and lower fences which are outliers. Mark data points beyond either outer fences and those are extremes. Extremes: are data outside both pairs of fences.
