Parametric tests were preceded by tests of their assumptions (normal distribution and homogeneityofvariance). Data distributions were examined for normality and homogeneityofvariance. Homogeneityofvariance was assessed by visual inspection of residual plots. No violation against the assumption of homogeneityofvariance was detected. For all analyses, standardized residuals were plotted against fitted values to assess homogeneityofvariance. Data were ln-transformed before analysis to satisfy the homogeneityofvariance. Homogeneityofvariance in the two-sample means test. The numbers of termites were log transformed to increase homogeneityofvariance. Data were tested for normality and homogeneityofvariance (standard transformations were applied where necessary). Levene's test for homogeneityofvariance was significant. Following tests for normality and homogeneityofvariance, data for all variables scored were found to be normal. Results of the evaluation of the assumptions of normality of sampling distributions, linearity, and homogeneityofvariance were satisfactory for all of the variables and there were no obvious outliers. The numbers of termites sampled were natural-log transformed to improve homogeneityofvariance between treatments for statistical analyses. It is clear from an examination of the reported standard deviations that in many instances our analyses may have violated the assumption of homogeneityofvariance. Height and leaf area data were log-transformed to improved normality and homogeneityofvariance. Dependent variables were transformed as necessary to meet the model assumptions of normality of error and homogeneityofvariance. If necessary, data may be transformed, for example by taking logarithms, in order to effect this homogeneityofvariance or at least reduce heterogeneity. All tests were normally distributed and the homogeneityofvariance was evaluated to be equal in each residual plot. Second, the profound individual differences expected among young infants violate the assumption of equality of population variances (homogeneityofvariance) for most parametric tests. Homogeneityofvariance and normality of distribution were tested for all the variables and the data were transformed when necessary. These examples are from corpora and from sources on the web.
