EXAMPLE . 1. Consider the following data for average daily gain (ADG) by 12 pens of cattle fed three treatment diets: Trt 1 Trt 2 Trt 3 3.40 3.32 3.25 3.59 3.49 3.42 3.65 3.52 3.55 3.85 3.70 3.67Trt means 3.4725 3.6225 3.50752. If we do the ANOVA for this CRD, w21

The Randomized Block Design

The Randomized Block Design. Suppose a researcher is interested in how several treatments affect a continuous response variable (Y). The treatments may be the levels of a single factor or they may be the combinations of levels of several factors.

Randomized Experimental Design

Randomized Experimental Design. What is an Experiment?. Campbell & Stanley stressed random assignment to experimental treatments. I stress manipulation of the independent variable. Quasi-Experiments: C&S’s term for research where there is a manipulated IV but not random assignment to groups.
