This shows the V and Z points plotted on the test template.

The template has two axes and two sloping lines. The horizontal axis is labeled V with a scale 0, 4, 8. The vertical axis is labeled Z and has scale minus 4, minus 2, 0, 2, 4, 6. A solid line runs from V = 0 and Z = 3.2 to V = 7 and Z = 6. The area above this line is labeled "Significant: experimental treatment better". A solid line runs from V = 0 and Z = minus 3.2 to V = 1 and Z = minus 1.8. The area below this line is labeled "Significant: experimental treatment worse". This line continues as a broken line from V = 1 and Z = minus 1.8 to V = 7 and Z = 6. The area below this broken part of the line is labeled "Not significant". Points are shown at V = 0.25 and Z = 0.57, V = 1.23 and Z = 2.09, V = 1.97 and Z = 2.89, V = 2.97 and Z = 4.71. The last point is just below the boundary line.
