The mean values of the teachers’ perceptions of their principals’ leadership practice were obtained
by averaging the ratings on the corresponding items. Fifteen respondents who had answers missing
in their questionnaires were excluded in the following chi-square and ANOVA tests. Table 3 indicates
the frequencies of the leadership features which had the highest mean values in rating the
items with respect to the three types of leadership practice. Thirty-two of the 269 teachers involved
gave the same highest rating to two types of leadership practice, and 16 of them gave the same
highest rating to all the three types of leadership practice.
