TY - JOUR AU - Lazic, Stanley E. PY - 2008 DA - 2008/07/21 TI - Why we should use simpler models if the data allow this: relevance for ANOVA designs in experimental biology JO - BMC Physiology SP - 16 VL - 8 IS - 1 AB - Analysis of variance (ANOVA) is a common statistical technique in physiological research, and often one or more of the independent/predictor variables such as dose, time, or age, can be treated as a continuous, rather than a categorical variable during analysis – even if subjects were randomly assigned to treatment groups. While this is not common, there are a number of advantages of such an approach, including greater statistical power due to increased precision, a simpler and more informative interpretation of the results, greater parsimony, and transformation of the predictor variable is possible.
