The data should be collected in a way that ensures the data conformity to the level of theory (Klein et al. 1994). It is important to say the way that the data were collected refers to the level of measurement, which has to be congruent to the level of theory. As explained previously, the Values Scale and The Leadership Questionnaire were used in order to collect the data. These instruments were applied to individuals in each group. However, the responses were aggregated to obtain the group means. The fact that the measures were administered at the individual level could represent a risk to the research. Nonetheless, that data can be collected at a level below the target level of theory, and then be aggregated to the level of theory (Burstein, 1980). This is the point of view observed in this research. Note that the data were collected with both instruments at the individual level, and then aggregated to produce measures, that is, the Cultural Patterns and the Leadership Styles (Decide, Consult Individually, Consult Group, Facilitate, and Delegate) scores. Klein’s et al. (1994) suggests the level of statistical analysis should resemble the other two levels discussed previously. For those authors, statistical tests can be classified in two clusters: a) those that estimate the extent of agreement within a single group, and b) those that estimate the extent of agreement by contrasting within a between-group variance. This second category would include the different ANOVA forms and other statistical procedures. Thus, in the present study the statistical analyses are performed at the group level. Consequently, we believe that the level of theory, the level of measurement, and the level of statistical analysis can be considered congruent.
