Table III.

Linear mixed effect model output for response variable fo fitted by REML. The following factors are considered: (1) Style, (2) Room, (3) Panel, (4) (chronological task) Order, (5) Gender and the interaction between (6) Style and Gender, (7) Style and Order and (8) Style and Panel. For the intercept, for each fixed factor and interaction, the estimate, the standard error, the degrees of freedom, the test statistic, t and the p value are reported.
