Critter Plot SlidesCritter Plotting Measurement & Data Analysis Lab Quarter-Inch Precision Divide each inch into 4 equal sections. 1/4 One Quarter 1/2 Two Quarters 3/4 Three Quarters The Lab Ruler 0 1 2 1/4 1/2 3/4 Patterns repeat every whole inch! Anatomy of a Plot Number Line Our lab scale goes from 0 to 5. Every whole number and quarter is marked clearly. The "X" Mark Each "X" represents ONE specimen. We stack them if they have the same length. Labels Include a Title and Axis Label so researchers know exactly what the data represents.
