Witryna9 lis 2012 · For example, a measured value of 3.1 cm is close to the ‘true’ value of 3 cm. Precision is how close measurements are to each other. For example, measured values of 5.5, 5.6 and 5.7 cm are precise. It is important to know that you can have data that is precise, but not accurate and vice versa. WitrynaLet’s look at an example to see how blocking improves the precision of an experiment by reducing the unexplained variation. In this field trial, the yields (pounds per plot) of four strains of Gallipoli wheat were studied. During the design phase, the 20 experimental plots were grouped into five blocks (each containing 4 plots). graco rightguide booster seat
